I'm looking to replace the 3.73's in the rear of my 10bolt in my 89 TA. Sumitt wants to know if it is a Carrier series 1 or 2. Anyone know what this is?

Thanks

 

There is no 1 series . There are only 2 and 3 series for the 7.5 10 bolt. There is no way of knowing from the outside at this point if you have a 2 or 3 series. You will have to remove the cover and check it yourself. If the rear end originally had a 3.08 to 2.41 gear then it will be a 2 series. If it has a 3.23 to 4.10 then it will be a 3 series.
