ring gear id help
We just went to replace the ring and pinion in my 67 gto and found out it is a 12-bolt housing and it has a 10-bolt ring and carrier. Surprise! So the new gears I have will be reeturned to Summit, but we are trying to find out what to order. The numbers on the ring gear that came out of it are:
13A40 GM HY 236.
Can someone run these and tell me what it is? I have searched the forums and didn't get any answers so please help. I know someone can help.
