So I've made one attempt that didn't go so well. I glued the area between the rear glass and trunk last, and there was too much material left somehow and it bunched up. That was a show stopper. I ponyed up for another and have it laying on the top now. It doesn't look like it fits correctly as if it's cut too big.

Common installation issue, when I fit a roof for a vinyl install, using a pencil (no markers/ink) I draw a line dividing the roof in equal left/right halves, front to rear...I then fold the vinyl in half (left side to right side) this way I know the centerline of the vinyl (plus I'll pencil in the centerline on the backside of the vinyl), and the vehicles roof, I lay the folded vinyl on the centerline marked on the roof, then unfold the folded side so that the vinyl now lays centered side to side equally on the vehicle, now pull the vinyl forward or rearward to find the position that the vinyl fits favorably on the vehicle...

Now fold the vinyl left to right or right to left on itself on the centerline previously laid out, now mark a line on the centerline on the vehicle and the backside of the vinyl that indicates the fore/aft position desired, basically a cross line across the centerline marked on the vehicles roof and vinyl, this way you can return the vinyl exactly to the position that it lays best on the vehicle giving the desired fit

When I apply a vinyl top there's no stretching/pulling involved, the fit/application should be like applying a decal, slow/smoothly...I start by folding the vinyl again side to side so that it folded in half the long way passenger side to drivers side, I then lay it on the center line on the roof in it's folded position, I prefer to use 3M Super Spray adhesive, I'll spray from the centerline exposed down to where the vinyl roof's side heat bonded seam is located, I only spray the vehicles roof, not the vinyl backside, then slowly work over the folded side into the glue portion of the roof, when you get to the side bonded vinly seam, stop and fold over the remaining material from the side seam down, now proceed to the opposite side of the vehicle, fold over the unglued half of the vinyl onto the previously glued side, again spray glue from the exposed centerline down to the vinyl's side seam location on the roof, and now slowly apply the remaining center section of the vinyl roof again stopping once the side seam in glued down, again fold over the remaining material from the side seam down, you have now successfully applied just the center section of the vinyl, now proceed back to the first center side you applied, now you will work the area from the vinyl's bonded side seam down into the sail panels/roof gutter/A pillars/etc, once done, proceed to the opposite side and finish off gluing down that remaining area from the vinyl's bonded side seam down, now the dutchman panel area is last, if you didn't pull/stretch or dislocate the vinyl's position as it was initially folded/laid on the roof for installation, then the rear dutchman panel area is simply folded back over the rear window, the entire dutchman panel spray glued and the material applied left to right/right to left using one hand in a sweeping motion, and the other hand suspending the material in the air as it's being applied

Hope this helps

Here's a picture of the new vinyl

Mike, thanks the response. that's basically what I did the first time. In the directions from legendary, they say that after the top center section is done, to proceed to the dutchman area. I did the dutchman area last on my first attempt and had too much material between the seams in the dutchman area. As you can see above if I make sure the dutchman area is laying correctly, there's too much material on the sail panels. I've tried to adjust the vinyl either full forward or back and the extra material is still there. It is slightly better when I pull it all the ways back to the rear of the car as shown here.

To back up, the car is a 70, but has a roof from a 72. I don't think there's any difference in roofs though. Another strange thing is the first vinyl top was for a 70 challenger, it had alot of extra material along the edges. The new vinyl top is for a 72 and there is alot less material along the edges. The main thing is the extra material is in the sail panel area. Maybe the best choice is to send this top back and get another 70 top.....

I had the same issue with my Legendary top. It seems you that in order to get rid of the extra material in the sail panel area you have to move the top forward. On my car moving it forward caused it to be too short to go under the vinyl top trimon the dutchman panel. I'm not sure what the solution is other than trying to make another seam that is the least noticable.

Thanks Mike: I have to undo this one a previous builder messed up and completely redo it. Not looking forward to it.

Still in limbo or did you fix it ?

I made another seam at the dutchman panel where it was the narrowest. It is not a cure for sure but mine could not be made to fit any other way. If you tried to move it forward to get rid of the excess then it was short in the rear and the a pillars didn't line up. Mine is a 70 and the roof panel is original. I thought i was buying the best quality but I was lucky to get it to fit as good as it does.

Gotta do what ya gotta do in this case. I looked some and haven't seen any other supplier. I'm returning mine and taking a chance that another from legendary isn't as bad, hopefully it's not worse. My plan when I get my replacement is to start at the dutchman pan area, then glue the roof at the rear with about a 1" wide patch running side to side, then stretch the heck out of the top which will hopefully take some slack out of the sail panel area. Not sure what else to do other than what you did.

Well I got another top from legendary, and it wasn't any better. So I decided to give it a go. I started at the Dutchman area, then the sail panel, and about 6" of the top at the rear. I had to stretch the center area to take some of the slack out of the sides. I got it done, somehow.

I think you did a GREAT job ! Awesome !

Great job. I had the same issue with a Legendary on my 73. After reading the directions I had two friends come over to rassle with it and it still had excess and looked awful. Took it off, ordered a new one and had a local guy install it for me. It was worth the big bucks. Yours looks every bit as good as his installation.

You did good.See,that wasen't that bad after all.

Thanks for the comments. Yeah, looking back it was a piece of cake !
