IDring & pinion gears
 
I havee a ring & pinion and a posi unit that I believe came along with my '69 pace car (previous owner installed 4.10s). The ring gear has 3862691 14 43 5 69. It should be 3.55. Anybody know for sure? thanks

That's a 3:07 ring gear,dated May,1969.
Used during 1965-70,then changed to 3:08 in'71.
Companion pinion should be 3853003.

Comes out to 30714285 3:07 or round up to 3:08 in 1971, hope that helps. What he said.
