Hi.

Im about to buy several sheetmetal sections for E Bodies.

I was wondering how the quality compares between Goodmark and AMD.

Im not talking here about the older Goodmark sheetmetal repair sections, like the partial floor pans, quarter skings and 2 piece trunk floors. I know those old ones were pretty bad, with non crisp stampings, the floor pans and 2 piece trunk floor pans were horrible with very shallow stampings, all the ribbing on the floor pans were weak and not as deep as original.

However, I just purchased some Goodmark Cuda and Challenger full quarter panels and although not perfect, they are OK in my book and needed some adjutsing to fit right and maybe a little work to appear as crisp as the original parts, but they are definetly useable when you have an ABSOLUTELY TRASHED original quarter panel. If the original quarter panel is still good and only rusted or dented on isoltaed spots, I would defnitenly reccomend drilling out teh spot welds on the ropiginal taking it off the car,`performing the necessary repairs and hanging it back on.

Now on the Good mark full trunk floor pans, they are a HUGE improvement over the old 2 piece units. Id say they are very nice, a lot crisper and the ribbing stamped a lot deeper....but not quite as deep or crisp as original. Id say they got it 93% exact.

I havent seend the full E Body passenger compartment floor pans from Goodmark, but I suspect the quality might be just the same as their one piece trunk floors. PLEASE LET ME KNOW IF SOMEBODY KNOWS ABOUT THIS FOR SURE.

I have never held any AMD sheetmetal replacement parts in my hands. Id like to know how do their full Challenger and cuda quarter panels compare to the GOodmark units.

Also, Id like to know about the quality of the full trunk floors and full passenger compartment floors that AMD sells....and how do they compare to the Goodmark units.

Thanks and please let me know since >IM about to buy a bunch of sheetmetal parts for E Bodies-

I just replied to a similar thread on the Q&A. If you are looking for a one piece floor for a 70 Cuda, the Goodmark floor has the access holes for the shock towers in the wrong place. The AMD part is year specific with the holes in the right place...

AMD is 10 times better then Goodmark!!!

I bought some goodmark metal & it wasn`t even
close on fit. Called them & they said so. Called
amd & was told it would fit. Bought them & they
are dead on. I will not spend another dime with
goodmark. Amd is the only way to go in my opinion.

Can't help you with the Challenger, but I have the Cuda quarters (73) and they fit real well. I cannot see the difference between the factory and the Goodmarks. The gauge of the metal is a slightly thinner on the Goodmarks but in general, they look just fine.

I had done a post awhile back about the AMD pieces I had gotten for my 74 barracuda. Pic's are still up here on photobucket

Everything looked good, inner wheelhouses mated w/ the 1 piece trunk floor very well when held together. Rear deck filler pannel was spot on in width. I had no grinding marks or waves on my AMD quarters and on several forums it was posted the oblong holes for the quarter window wiskers/felts were too high on the goodmarks resulting in noticeable gap. I measured the distance from the top edge to those holes on my car, then measured the AMD pieces, and all the holes were the same distance or slightly lower so I if anything I may have to file the top edge of the hole some to get the felts to fit if they're too tight.

This is from a PM I got:
I bought the goodmark
quarters,outer wheel house & trunk ext. The
quarters seem to fit ok. The outer wheel house wasn`t even close. The quarter was 1/2 inch from
meeting the rocker. The trunk ext needed a lot
of work. I bought AMD outer wheel houses & they
are dead on. I am going to buy the trunk ext from amd when I get that far. It appears that the amd
stuff requires a lot less work. I don`t think I
will ever buy from goodmark again.

I used the goodmrak quarter panels, the outer wheel houses and the trunk floor extensions.

I think they all fit fairly well.

The outer wheel houses and trunk floor extensions did need a little bit of adjustments for them to making fit the quarter panels snugly, but it really wasnt a big deal. I guess that if you have ZERO bodywork abbilituies it might prove a hassle, but to anybody who has marginal bodywork skills its a piece of cake.

What I could see though is well, that the trunk floor extensions are not crisp stampings...they have the "washed off" look. The ribs are not crisp and deep, they are shallow, that would be my only compaint really.

On the quarter panels, I could see that the stamping for the "fuel" gas lid on the pass side quarter panel leaves a lot to be desired. I dont know if the AMD Challenger quarters are better in that respect than the Goodmarks. I had to work on that section to make it look original.

Also, the overall contour of the quarter panel from the center bodyline towards the upper part of the quarter panel was a lot flatter on the Goodmark than on my MINT ORIGINAL quarter panel on my oruiginal paint 70 Challneger. I used a profile comparator and it was not even close, and you can spot it when its on the car if you are familiar with the Challenger's body lines and have seen MINT Challenger bodies b4. I had to fix that and after that it looked pretty much like an original quarter, but to be perfect, or at least close to it....they do need some work.

I havent paid attention to the oval holes for the window felts, but nopw that you've brought that up I will go back and take a look.

I wonder how the profiles and contours on an AMD quarter compare to an original quarter, and how do the stamping for the gas cap looks.

I also have 70-71 cuda goodmark quarter panels but have nopt installed them yet...IM getting a mint 71 cuda body shell soon, so Ill be able to post here what are the shortcomings of the cuda goodmark quarters.

Oh...and about the Challenger deck filler from Goodmark....I think it's OK...but I had to adjust the ends cause I dont remember if it was too wide, or if it was too narrow....

Then again, I think it's minor and I would not blame that to it being off....since these cars got assembled with pretty loose tolerances I guess that what may be too narrow for a particular car may be OK for the another one, so all in all, I think that the deck filler from Goodmark is OK.

Oh I also got a Challenger trunk lid from Goodmark. On this part I think it's OK to use it but only if you dont have access to a nice original trunk lid. The Goodmark trunk lid is a bit wavy, the underbracing is kinda cheesy, the edges for the undebrace holes are wavy and the edges are sometimes sharp, seems like when they assembled the 2 pieces together they banged the underbrace witha rubber mallet or something so it has quite a few dents that will need to be smoothed out with body filler, the skin flanges that wrap around the undebrace are not even and towards the corners they kinda splayed so I had to but a straigh edge on the borders of the trunk lid and where it was not straight and square (like I said, specially towards the corner, I had to heat up and bodywork it so I would make em nice and square). Next time Ill just go on and try to find a clean original trunk lid.

Here is the 72 340 4 speed Ev2 black guts AC car thats having all the body done.

Here is the original roof skin, I preffered to take it out, patch it up, bodywork it and reintall it rather than getting a repro. I believe that anytime when this can be done to an original part its better than getting a repro part. I advice only to get repro parts when the original panel is really totally trashed.

About the problem with the fuel cap, that area is covered with the flip top but I did have to notch the 4 corners of the flip to cap housing to get a flush fit. This took all of 5 min and the housing fit perfect. Did you notice the body line around the wheel well on the Goodmark quarters ?? The line fades out on the top of the wheelwell. That line is way crisper on orig panels. The front fenders by Goodmark for the Challenger have this same problem. I have seen the AMD Challenger quarters at Carlisle and they looked better IMHO.
