G707 tach drive diesel

[fdt860]

I have a GVI and Would like to add a tach. Diesels 707 have a generator tach drive.
The PN is impossible to find in the online parts book.
Would a delco tach drive from a Corvette work? Or a Ford tractor one?
Thanks!

Gv1 uses same Stewart Warner drive as G705//6/ if diesel. You are working with ratios. Tach has to match drive.

Thank you for the info. I cannot find parts numbers or pictures in the tractors before the G707. Are you sure some GVI diesels came from factory with a tach? Do you have pictures?

My G704 has a generator tach 1962. It replaced GV1. Gv1 lp had tach and diesel used Hobbs hourmeter driven off oil pressure gauge. G705/6/7 as well as Massey 97, used gererator driven. Part # for drive is 10A19238. Am sure NLA.
