ok I didn't read that anyone said this yet. By going to the 86 frame you saveing a bigg headache in not only saving time from the EFI wireing but you also have the IFS steering box on it. If you want you can hire me to make a crossmember to save money. Put the rears up front and to save money put blocks and shackles in the rear. Its really not hard to do a SAS. Engine issues can be a pain and get you frustrated very fast. My vote is just part out the 84 and just keep the axle and transfercase from it for yourself.

i have decided to run chevys and rears on the ifs frame, meaning i would have to move the ifs box anyways. where do you live, if you made me a crassmember i might get killed for shipping. i'm with your idea to part out the 84' but i don't know about the t-case, its a forward shift. i've heard there a kit to make it top shift but would't it be better to find another topshift tcase in my area. PM me if you want any parts off the 84, its a pos so bodyparts are only half there. By the way thats an awsome 4runner in your avatar.
