Building a '99 4runner - Pirate4x4.Com : 4x4 and Off-Road Forum

PARTYHOUND · 01-28-2010, 02:14 PM

I found a 99 4runner with about 80K on the clock for $1,000. It was involved in an accident that trashed the rear suspension, bent the rear axle to about a 45* angle and some body damage. A couple of doors need to be replaced, a new windshield (the windshield frame is fine), and maybe a few other things cosmetic wise, but that's not important. The thing seems to run like a champ, it's only got 80-something thousand miles. I want to pull my dual transfer cases out of my 82 pickup, my axles, steering linkage, etc and put them under this '99. I realize that I'll have to build some mounting points for the springs and a cross-member for the front...no big deal. Will my transfer case (that is currently bolted up to a G54 or G56 tranny) bolt up to the tranny in this 4Runner? It's a 5 speed tranny that is in it, but I dont' know much about these newer rigs and what works with what. Any help would be appreciated!

Your 4cyl tcase is 21spline, and the R series trans from the 994runner is 23 spline you need 23 spline conversion kit as well as a adapter for 4cyl tcase to R series trans, get these as well as helpfull tips from, Marlin, or Inchworm.

Definitely contact Marlin. The 99 is currently driver's side diff, but if you SAS it you can go pass side with some exhaust mods. Definitely doable though. Good luck.

You'll need a 3.4 v6 adapter. Inchworm's is clockable 10* for a pass. drop case if you want to drop in the duals from your '82. Marlin's is only clockable for a driver's drop case. Either way you will need a 23 spline input.

And most likely, Inchworm will be much easier to get accurate info out of over the phone.
