Toyota truck rear strait axle and 2 speed powerglide and hang on !! thats how the mud dragters do it and have seen many toyota axles get very punished with high hp and they hold up well for independat diff whould use 300 zx or early jag diff with inbord brakes

That sounds like a fun rig, I love those old 2 speed powerglides, damn near indestructible.

Have seen a 2 speed power glide take 1500hp + even thinking about one in buggy with chain drive and rear diff in front the 2 speed power glide is about 150 lbs lighter than the 4eat i run now that i only use 1rst and 2nd anyway
