Transfer case ID help

[Blue60]

Trying to confirm/deny what year my tranfer case is. It's off what I thought was an original 2/79 FJ40. I have a transmission shop doing a rebuild of the tranny and transfer case during my frame-off. Keeps getting the wrong kit...his tech supplier says the transfer is a 74 year model. I wasn't prepared to agree or disagree until I did a little background research.

Best I can tell from the tech links here: the 79 will have the fully raised support ring for the idler shaft, and will have a 27 spline front output shaft. That should be rather conclusive when I go look at it tomorrow, (along with the pictures to help me!)

Any other thoughts or recommendations to add? Appreciate!

Cheers,

Dave

P.S.

How does one determine year of a 4 speed transmission?

How does one determine year of a 4 speed transmission?

Couple ways:

Green connectored switch on top of tranny with single wire connector=8/'76-1/'79

Rear bearing cover with a bolt on the very bottom=4/'76 and newer

PTO side cover=4/'76 and earlier only

Aside from that, you arent going to get more specific
