This came out of a '67 Chevelle but, it's obviously a BOP rear. It's 3.91 ratio TH code 4 pinion posi. I've seen some mention of the TH code being '67 Olds 3.91 posi and some lists don't mention a TH at all. Any help to confirm is greatly appreciated.

 

 

TH is the correct code for 66/67 8.2 B/P axle. The one pictured is a 67 due to the spring mount pad.

 

Thank you.
