I will do a closer check, but a rough next-to-each-other check sure seemed like they were the same diameter and depth....but I'll do a check and take some pics.

Finished repairing my tub and bolted it back up at the longest length for the front supporting bolts.
My new 205/70R15 on spare (on a 7" rim) fits easily.
I cannot get it to latch with the 235/60R15 (on 8" riims) tires.
I would think that front bolts that were an inch (1") longer would make it all fit. The exhaust is still slightly below the tub so that wouldn't be so terrible.

Here is what I ended up with...probably way overkill but seems to have enough extra length to put a 235 in there.

I like it. I should probably just do that before I put if off forever again.......
How long is it from the frame to the bottom of the bracket?

5 1/2 inches from the frame to the end of the bolt. About 1/2 inch threaded into the frame.

Thanks. If I get ambitious I'll go look at all-thread tomorrow.... 5.5" doesn't seem much longer than my bolts....I'll measure tomorrow.

Don't forget the single rear attachment can be adjusted as well.
