If it is the same as the North American V6 4Runner then the door coded should rear "G" which is the 8" rear.
This should help... http://www.brian894x4.com/Gearratiosanddiffs.html
I am glad this thread exists... It gives me a few ideas on how to upgrade my 12t press... The only thing that I didn't see is someone making it a bit taller, as it is it barley removes axle bearings from a 2nd gen runner shaft.
Nice score on the stick machine... The old ones were certainly built to last. I love my old Forney, I picked it up a few years ago for $50. And I know what you mean about heavy!
Looking for someone fairly local to me (Belleville On Ca) that has a set of rear Lc80 coils they want to part with. They are to be used on the rear of my 4Runner.
Thanks Larry
