GM Gears : 2.73
A decent set of OEM GM gears.
These came out of my 1986 Trans Am and were the stock gearset it had in it. I pulled them out and replaced them with a different ratio at around 80K miles.
There was no whine or issues with them when they were removed.
They have been stored in the foam packing and box the aftermarket gears I bought came in.
Ratio is 2.73:1
Fitment is 7.5" or 7.625"
Specifically the 86 diffy is a 7 5/8" or 7.625". As you can see GM stamped them as 7 5/8".
Pattern looks fine on the mating surfaces. I got some closeup pics of the numbers and the pattern.
Would like $50 + shipping
Pics :
----------
I have closeup pics of the wear pattern on both gears
I have closeup pics of the ID numbers on both gears.
PM me for those
