Good news, bad news.
yes you can fit 10 bolts under a scout II just fine. getting them to work is the hard part.
bad news
(experience speaking)
The 10b front will fit under the scout and bolt up if you reverse the pin in your spring pack (scout springs, makes it spring over axle). The distance between spring perch centers in not much.
you will need crossover steering to get the GM axles to work in a scout!
basically you are doing 2 major changes at one time. crossover steering and spring over axle. on my truck I got half way through with it and decided to just buy a new GM style frame instead of messing with the scout frame on my 1945 chevy.
I payed 100 for a blazer frame with 4-6" lift kit on it already and used my 3/4 ton axles. much cheaper than using scout crap and cobble building.
just use common sense in your build it can work it was just more money than I had at the time
