The new 4runner project

I am going to pick up my 91 4wd 4runner in the next few weeks. I am also getting a 4.3 engine trans, and harness for this build. I am looking for an rx7 IRS, and a 2wd front clip.


My question is are the pre 89-95 yotas the same front suspension ? Or should I just only look for a 89-95 style ? Also considering just building a full frame since this is going to be firewall back anyways. I will post pics as soon as I get started on it. This is going to be a process, I am going to shoot for having a roller at ITB but if not I want it to be a LOATP 09.
