Problem fitting a 15x10 inch rim on an E Body.

Problem fitting a 15x10 inch rim on an E Body. - 03/22/14 09:52 PM

I am trying to go with a larger rear wheel and tire on my 1970 Barracuda. I have a Dana 60 (Strange S60) with the B Body Brackets and off set rear springs. I was planning on using Vintiques Rally wheels 15 x 10 with a 5.5 inch offset. Currently I have a 15 x 8 with a 4.5 offset. I got the wheels but the fitment looks wrong (fender side)....

Tape a large piece of cardboard to the floor under the brake hub and plumb bob all the key points onto it. The leaf spring line, wheel well lip, hub face, etc. Then you can easily measure all the opening you have available and the backspace that will work.

I have 10" Cragars with 28x12 MTs in the wheel wells of my Cuda.

P.S. I have a '66 B body 8 3/4 in the car.

Is your rear width E or B body width?

It'll work either way. I run them on a challenger with E body width rear end. I had to clearance the inside fender flange on one side to clear the sidewall of the tire during spirited driving.

Next time I'm using a B body width rear end and it would be perfect with 15X10" wheels with 5.5" BS.

Me too, but they do fit.

68 to 70 B body rear end and dr diff relocators will fit a 15x10 with 5.5" backspace. That's what's under my car with a 325/50 M/T drag radial. Had to roll the lips to fit that much tire, but that doesn't bother me with my junk.

I have the B Body rear with Dr. Diff offets as well....from the outer lip of my rim I can barely fit a yardstick to the fender lip....

What year is the B-body rear?

It was built by Strange so it is an S60.

Are the wheels 15x10 with 5.5" backspacing?

That appears to be a lot of inside clearance but that might change depending on the tire size.

I'm planning on installing a 1970 B body rear under the wife's Challenger.

The rims for the rear I bought many many years ago and are custom built Torque Thrusts 15x10" with 5.75" back spacing.

The extra 1/4" of back spacing should help keep the tire away from inside of the quarter panels.

I have 325/50-15 BFG drag radials for the car.

I was anticipating tinking with different thickness wheel spacers to get the rims perfectly centered, I would love to have all the inside clearance your picture shows.

Yes the Rim is a 15 x 10 with 5.5" clearance. I am looking through my Strange Engineering receipt the axles were cut to 29 3/8 and 30 3/4....not sure what a B Body is

Thanks for that info.....that would explain why it is too tight....

I don't know the specs for an E body

Maybe it was built to the E-body spec ?

if you look at the posted pic
you may notice the weighted strings hanging at the inner tires

drop some string down from the wheel flange, to the floor
to get the full width of that rear end

I think the E Body Spec is 30 and 31 but I am not positive...and since the rear is 3 years old...lol Funny part is that they put the correct B Body pads on it as it matched the offset kit just fine. I appreciate the help from everyone....I will have to stick to a 8" rim with as big a tire as I can fit.

Yea,when we put the moser rear under the rampage (2010)

the Sales person at that time
asked if I wanted the ford/dodge housing ends on the rear.

I didn't think anything about it until
we went to set the 8 3/4 alum carrier into a 9" (ford)housing flange

See if your axles have extra spline length and can be shortened some more. Many times aftermarket axles can be cut down another inch.
Looks like you have the 10" wheels and that is your goal, I'd see if I could cold cut another 1" off each axle and then have the housing shortened 2".

Or return your rims and get 6.5" backspacing. Or have the backspacing changed on your rims to 6.5".

You rims will not look at deep when viewed from the side though. If you are running rallye rims, they will end up looking just like a typical 15x8 with 4.5 backspacing.

i am going to call on that tomorrow to see if they will do a custom backspacing in this rim (it is not listed in their catalog. I know I can put a 295/65/15 on an 8 inch rim - at least the manufacture lists that I can (MT Drag Radial) just wondering how much further out the tire will be on my current rim 15x8 4.5 Backspacing with regards to the fender....

So you've got the B body rear perches and offset shackles...It looks like you've got a bunch of room to go on the inside....At this point would'nt getting the proper backspacing for the 10 inch rim give you what you were shooting for from the beginning ??? Why go back to an 8 inch rim now ???

Re: Problem fitting a 15x10 inch rim on an E Body. - 03/24/14 02:51 AM

Sounds like you have an E-body rear with (B-body spec) 44" spring perches.

If this is correct, you need 10" wheels with 6 1/8" backspacing.
