Which TC would I want to use for the following scenerios given either a 1971 FJ40 TC or a 1976 FJ40 TC:

1. Behind a 700r4 Tranny (1972 Stock axles), and want to roll down the highway with comfortable SBC RPMs @ 70 mph?

2. Behind a 700r4 Tranny (1972 Stock axles)and do not care about going any faster than 60 MPH on highway, but want good crawl speed?

Thanks for helping the Newbie in advance.

Both cases have a 1:1 top gear.


A 1971 case will have a 2.313 low range

A 1976 case will have a 1.99 low range

Thanks Poser.

With your advise I tracked down Kurt @ Criuser Outfitters. He found the gear to make a later box mate to a course input shaft. As dumb luck would have it my buddy showed up with an early box this evening. I was curious which box I should put in. Nice to have a back-up either way though.

Again thanks out to Poser and Kurt.
