    cruiserparts.net sells 3rd members w/ 4.10 for 250ea shipped. Not too bad when you consider shipping cost of 35-50 ea. I had a set a while ago for sale and had no takers on them. I think I was asking 400 for the set or something. Ended up just putting them in my truck instead.

    As for sell the 3.70, I'd say $100 ea or so, if you can find someone who wants to gear up.

    Course spline pinion is usually $50-75. Fine spline pinion is usually $200-250. Fine spline will be stronger and you can re-use your existing driveshafts.

    I've got 4:11 in mine and wouldn't mind stepping down to a 3:70. email me if you want. tjdiv@hotmail.com

    Before I get too far, the third members should be interchangeable from a 1970 with 4:11's right?

    Unless your old school like me and still have coarse spline. In which case the prices switch and Randy's sends you the wrong R & P :mad: :D

    [/quote]Through 12/78 was 4.11. 1/79 and up FJ40's and all FJ60's were 3.70. FJ62's went back to 4.11. 78 FJ40's and all FJ62's were fine spline pinions. I don't know the month in 78 those started.

    There were supposedly optional ratios in very early FJ40's, but all of the US spec 40's I've ever heard of were 4.11 (thru 12/78).
