2.73 gears for a 12 bolt
 

I know a guy who is looking for a NOS 2.73 for a 12 bolt. Since it's not a popular ratio I figured that there are probably some out there that haven't been used yet. Please let me know if you have a set.

Hey Freddie,
Best I can do is a set of NOS 3:08’s dated 1967
Have a set of used 2:73
Probably going to be pretty tough but I have seen them
Years ago so maybe

Thanks. I've got a nice set of used 2.73s, but he's looking for a NOS set. He has 3.07s in it now.

I may know someone with a set of nos 273 gears. ill call him today

OK. Maybe the guy is still interested. I shipped the used gears that I have today, but he might still want a NOS set.

I called the guy with the Nos gm 273 gear set. I should go look at them as they are 5 miles from my house. I knew he had them from a previous conversation. Who is the interested party ? call or text me 815-483-5584 brian

I looked up the GM part number for the 2.73 12 bolt ring and pinion gears.

There are two part numbers in Group 5.529

3875267 shows for 65-68 Pass and 67-68 Camaro.

3961435 shows for all 1969. Those gears are 3869788 and 3869785

This guy on eBay has a set of 3875267 NOS. You must click "See full item description"
