im wanting to buy a locker for my car but am unsure on my carrier size. i know i have 3.42 gears, its a govlock rear axle. and is original to the car and is correct through the rpo codes. the car was originally a v6.

 

If I understand the question correctly, you need to order a locker for a 7.5" 10 bolt with 26 spline axles.

 

that's what I needed thank you

 

If it's a '86 rear end then the 26 spline will be correct. You need a 3 series to work with the 3.42 gears. If you are looking at one of the Power Trax lockers then it will not work in the Governor Lock differential case. You will have to swap the differential case for a standard 3 series before you can instal the locker.

 

Probably not.

I bet you're going to remove the cover and post pictures though.

 

its an original 3.42 car. The gears were in it from the factory.but I didntknow the gov lock case was dkfferent.

 

ill post pictures if needed. Id like to know what it is before I rip it out.

 

The 10-Bolt FAQ at the top of the page has pics. My 'guess' is that the car is equipped with an Auburn.

V6 cars usually had a standard differential. It would have been a special order if it has anything else.
