I had a factory toyota axle with all the goodies at mcr7 and it had me wanting more width. Now some might say thats what wheel spacers or 2.5 bs wheels are for but didnt feel comfortable witht that. So i went with a diamond housing and they are sweet. I wish i would have done it from the beginning. But everything depends on $$$$. If i could do it over i would have my exact axle and maybe try a HP e-locker instead of the HP detroit. But i am building a 87 4runner for my dad and he wanted to save money and use a 85 front housing and he will be running a 22re, duals and 37" mtr's.
