So I just bought a 68 Post Coronet and also bought a k member with disc brakes attatched to them. I know it's factory chrysler but the guy said it was an ebody and that it would be the same and work. I just read the other post about the ebody k member and that the steering was different. I pulled the numbers off the motor mount and was wondering what I have? They where not the greatest stampin but I was able to read MK34631 or MK84631. I measured the rear mounting holes and they measured just under 34 inches. From the right rear mounting hole to the left front hole it measured 36 1/2. Both of these where measured from center to center.

I think you need to look at the front lip of the K frame to see if it has the holes to mount the sway bar. There should be two holes on each side if it's a '69 & before.

I looked at the k member and no holes in the front of it. It also does not have the center hole for the sway bar to pass through either. I am pretty sure my 69 charger I had did not have the front mounting holes either. Are the numbers on the left front engine mount the ones I need to look at to id it correctly?

If it doesn't have the provisions for the pass-thru sway bar - then it isn't e-body.

The motor mounts are not body dependant.

Single piston calipers? Are you sure it isn't a-body?

pictures please!

I will post some tonight!

The pin-type calipers were used on early 70s B and E bodies (I'm not sure when they changed to slider calipers on B/Es, but the sliders came out in 73 on A-bodies). It is likely that you have an E-body setup there.

So since I bought this for my coronet big block car I would just need to get a b body big block k member and the contol arms and brakes from this would swap right over because they are the same, correct?

Without reading the entire post from what I see you may have a '68 early '69 V8 (non-Hemi) K-frame with the 4-holes (2-each side front) for the '68/'69 swaybar and NO swaybar end/link mounts on the Lower Control Arm (LCA). That is not an E-body K-frame. You need the LCA's with the swaybar mounts and it should work for any V8 Mopar engine of that era.

This is the later '69 K-frame that started to change over to the '70 swaybar routing through the K-frame and still has the 4-holes at the front for the '68/'69 swaybar mounting like I think I see in you K-frame photo.

Kind of hard to tell exactly, but looking at the rotors...it appears to be from a 70-72 B or E-body. I say that because the rotors look like the 2 piece design.You can buy a spindle sleeve from Dr. Diff so that you can use the later 1 piece rotors that are a LOT cheaper and easy to get. So yes...the brakes will work. If it were me, I would make a way to get both k frames level (both ways)and check the angle of the steering box mount plate. I did that with a 70 Roadrunner k frame and a 70 Challenger k frame a few years ago, and there was 2 degrees difference in the angle of the box. I think the e body was 23 degrees, and the b was 25 degrees. Would that make a difference as far as wearing out steering column joints? People here have used different body style k frames in cars and didn't seem to have problems. Check around some more before you go buy another k frame. No need to worry about it being from a big block as long as it's from a V8 car. Unless it's a Hemi k frame, they will all fit big or small block. The difference is in the brackets that actually bolt to the motor. That's my , so good luck.

This top mount on the LCA is what you need to put a swaybar on but I can't or don't see it in your photo........from what I know all of the V8 B-body K-frames were the same (except for skid plates on the Hemi for the oil pan??), the engine mounts are different too but you knew that....

Check the K-frame date on the front (see the photo with the text above for the location) that will tell you (roughly) what you have. If it's a xxx8 x number (think in '68 some were stamped upside down too so there's another clue) and you have a fender tag with a Scheduled Production Date and both numbers are close then it's the original K-frame IMO.

MikeR

Sorry was in a real rush when I read (re; skimmed) the original post and maybe the date stamp will give you a clue but if it is an E-body as posted the steering box angle will (might??) be a problem. Can you see the production date stamp on it, again sorry for not reading the entire post.

So I scoured the k member for new numbers. I did not find anything in the front or the back but I did find some numbers on the top and the bottom. If you are looking down on it from the top right next to that tiny hole in the top of it that is covered by the oil pan it says M 1565. If you are looking up at it right next to where the two sheets of metal meet below the hole up top it says MK45-1 and LMK 45-1. Hope this rings a bell with someone!

any help ????

If it is the 65-69 b body then it is a small block/big block because it is not like the slant k member in the car currently. Any body else think this is the b body v 8 k member I need for my 68 coronet?

So I'll throw this in to further complicate things... The brake dust shields aren't 70-72 B & E.. In fact the rounded shape of the rotor to hub area looks wrong as well....

On the rotors I wish the pictures was clearer & also I wish I had a picture of a 70-72 rotor... Just doesn't look right to me... The dust shields I know 100% the 70-72 B & E shields are smooth, 73 & up have the ripples and I believe 69-72 C body brakes have it too... Those rotors kind of remind me of C body rotors as well.... I once adapted C body rotors to E body spindles, it can be done....

Looks like 11.75" rotors.

Compare your rotors to the rotor in this post....

Will do! I will not be able to do this for a few days but I will get back to this and hopefully we can get to the bottom of this!
