CudaGuy, I have a 70 b body 8 3/4 under my Cuda with 325/50/15s on a 10" rim with 5.5" bs. Stock wheel wells. They fit but it is tight. I had to shave the lip completely off. They will rub the fender wells slightly if I go around a corner too fast. Raising the rear 1/2" would eliminate that but I dig the lower stance.

6packcuda, thank you for the reply.  When you say had to shave the lip completely off, do you mean the inner lip inside the wheel well above the tire or the folded lip attached to the quarter panel?  Thanks again!

The quarter panel lip had to be trimmed extensively towards the top of the wheel opening.

What kind of room do you have to the springs? I'm guessing that you're using a 1" spring offset kit with that B body rear?

Yes, I used the Dr. Diff 1" spring re-location kit. Everything I read and Dr Diff himself told me everything would clear the springs fine with my set up but, for whatever reason, after I got it all bolted together, the tires did not even come close to clearing the springs. I had to modify the shackles to move the springs in another 1.5" in the rear. Because of that, I also had to re-locate the spring perches. I've racked my brain trying to figure out what is different but no luck. After my modifications I have about 1/2" clearance to the springs.

I have 315's with the 1.5" offset shackles from Cass under my car. Lots of room. 3/8-1/2" clearance from the springs 3/4" or so to the quarter lip. No rolling needed for me.

 Despite what the mopar book says, 62-65, 66-67, and 68-70 b body rears are all different widths. This will directly impact where the wheel assembly ends up which will then impact rim  offset selection.

Very true, but the '70 he says he's using is the widest of all of them. Unless it's not actually a '70 B body rear end. A '68-'70 8 3/4 B rear should be 60 1/8" drum to drum (54 15/16" flange to flange), a 65-67 8 3/4 B rear should be 59 1/2" drum to drum (54 1/4" flange to flange).

'62-63 and '64 were also different widths, but I usually don't pay much attention to those because they have tapered axles, the kind that has the drums retained by a nut on a taper with a keyway.

So it very well could be that B body rear wasn't actually '70, but a 65-67, which would need less backspace.

It's a '70. I had to order the '70 only brake lines for it. The vent/T fitting is in a different location on a '70.

I have read most of this topic  and found lots of good information, but not that fits my situation.
I have a 73 cuda with stock e-body rearend. A street lynx 4-link wit the lower link bars attaching at the stock location. No mini tub, sock wheel wells. Ran out of money, will mini tub later on. Anyone have this setup. Can I fit a 15x10 wheel with 6.5  BS and a  315 wide tire?
Thanks Jimmy

I made a spreadsheet of all the combo listed in this thread.  There is one entry that has Street Lynx, member lotsapins owns the car:

R 18x10 5.5" 285 40 18 street lynx suspension lotsapins

I don't know much beyond this.  Maybe he'll chime in?

Any chance of getting you to share that spreadsheet?  :bigsmile:

Yes, I can do that.  I'll put it on Google Drive.

I think that worked. I was able to see it, at least. I'll try to download it at home tonight.
