RARE early 1965 dated 12 bolt GM 4.88:1 gears - ring & pinion 3961404 3862528 3862516
 

Hi Everyone,

I have a set of RARE early 1964 / 1965 dated GM 4.88 gears as shown for a 12 bolt. recent take out parts which are nice as shown.

Ring is dated 11 64 part number (as shown) is 3862528 8 39 which of course means 4.88

Pinion is dated 2 69 part number (as shown) is 3862516 8 39 which of course means 4.88

GM part number is 3961404

The teeth count is 39/8

These early dates are super rare for the first year of the 12 bolt. Looks like there was once some light surface rust on two or three ring gear teeth, but IMHO, it looks minor and likely a non-issue; see photos.

SOLD

Thanks,
Anthony
