Ranger is closer in width. You narrow the wider side to the short-side spec and use 2 short-side axles and it ends up 2" wider than an S-10. I have done this on my '96 and I run a 325-50 tire on 10" rim with 5.5" backspacing.

That said, if I were to do it over I'd use the Explorer axle with 31 splines (you can only get the Ranger in 28 splines). The cost wouldn't be that much more, maybe an added $250 or so.

Hey runn,
check out my swap write-up I did a few years back. Here it is - Ford 8.8 swap. I've been running the 8.8 for a while now and it's been awesome. It is wider by a margin... about 6" total or 3" per side. The leaf spring mounts to line up well though. Since I was on a budget, I opted for this swap and just offset most of the width difference by using wheels with larger backspacing. If you want to take it a step farther, the diff is offset by about 2.25" which means you can cut the housing on the long side and use another short side axle as a cheap way of narrowing it without needing custom axles. It will still be a bid wider but it will help.

Other than that there are very limited options for the S-10. The stock rear is extremely narrow compared to most other applications. I've heard of mythical 9inchers from older broncos that are about the right width but I've never found one. Other than that you can also try to scavenge for an 8.5" out of a newer S-10 4.3HO... once again very rare and I believe they only came with 3.08 gears and open diff, so factor in a gear and posi swap. Beyond that you'll have to pony some cash for a shortening. Hope that helps.

I do have a 9" from the old Bronco and they measure 58" from flange to flange for the mounting flange of the wheel. Forgot for the moment what the wheel to wheel flange for the s10 is.

Ok well in that case it sounds like even the bronco rear is too wide. I don't remember what the S-10 is from wheel flange to wheel flange but it's 48" from backing plate to backing plate

edit: looks like it's about 54" at the wheel mounting surface. The explorer 8.8 is about 59 3/4" at the flanges. So the bronco 9" would be even a little closer than the 8.8, although I don't know about the spring perches?
