We have a '73 Commando we recently acquired running SOA on trashed leafs and a 3" BL (terrible, I know). We will be (and actually just did) running it in the Small Tire Street class in 4x4cross mud slings. This limits a maximum of a 33" tire. The Commando uses a 304 V8, 400 Turbo trans, a Dana 20, and is currently equipped with a Dana 30 up front and what I believe is a Toyota 8" in the rear. Both are welded. I have zero confidence in the current setup and am looking for some options on what would be better. I'm thinking looking for a front 44 out of a '73-'77 3/4 or 1/2 ton Chevy and the 10 or 12 bolt that would be in the rear, or a pair of Waggy 44s. We already have a Dodge 60 but that's a little big for 33's. Also have a spare 8.8 but I'm fairly confident it would be far too narrow. So, options and opinions?
Also, if anyone knows what leafs from a junkyard would be a direct swap, that would be insanely helpful.
