Whos running 275/60r15. Having issues
Narrower than the 8 3/4"? The 8 1/4"? That is news to me.
Thanks for all of the replies. I guess I didn't realize that the 8.25 was a different length than the 8.75. So I guess I'll get it in the car and see if I have room for a small spacer until I get around to getting the correct rims. If not I guess I'll have to relocate the springs or go with a different tire.
I have an 8.25" A body axle in my Barracuda on stock rebuilt rear suspension, leaf springs bushings ect, and I have that tire/wheel combination on my car. It works fine, I laid it all out on the computer. I had my 15 X 8 rear wheels built with 4.25" backspace as I remember. I have about 2600 miles on this combination with no sign of any rubbing inside or outside.

The 8.25" housing is actually wider back plate to back plate than the 7.25 or the 8.75 housing. I think that is how I was able to make mine work.
There are about 4 different widths for A-body rear axles depending on what you've got. Going by the wheel mounting surface width, or hub to hub-
The original SBP 8 3/4 is
57 1/8"
BBP axles in the original 8 3/4 housing gets you ~
57 13/16"
The 73+ BBP 7.25 and 8.25" rear axles are
56 3/4"
And from what I understand, the pre-73 SBP 7.25 is different again, closer to the SBP 8 3/4. But I haven't had one to measure to confirm.

So sounds like spacer are the way to go then. For those that have used them is there any you recommend?
Nothing wrong with spacers at all as long as you get good ones. I use billet spacers that have the holes drilled to fit the diameter of the studs being used, cast spacers with openings larger than the studs are not a good idea IMHO.
When you install them, you have to check some things to make sure they're properly installed. They have to sit FLAT on the hub/drum mounting surface. So make sure they're not hanging up on the center register or some kind of edge/ridge. And you have to check to make sure you have the proper thread engagement on your lug nuts. The thicker the spacer, the more likely it is that you'll need to install longer studs to get the proper thread engagement. It's nice if you can get a set that's hub centric to your wheels, but with the larger center register that Mopars use that's not usually easy to do. Most aftermarket wheels are lug centric anyway.
This set should fit, it has a 71.5mm center bore which should clear the factory center register. I haven't used this company before, the one I usually use doesn't make a 1/4" or 5/16" spacer unfortunately.
