Hello folks. My PHS did not specify gear ratio for the rear end. The PHS did say TH350. I posted a pic of the accumulator and pan codes. As for the 10.5, it was used starting with 2nd gen Birds so i am ok with it in my June 69 car. I plan to drop my gas tank for a last spot look for the cast sheet (checked everywhere else). Oh, and instead of drill THROUGH my gear selector cover to reattach it, i used neodymium magnets. It can be removed again if needed. I bought this from a car lot day after they took it in as a trade. I paid 15
