69 Camaro 12-Bolt Posi

[lowmile]

The 67-69 Camaro and 68-72 Nova rears are 53 1/4 flange to flange and the 70 up Camaro is 1 inch wider 54 1/4 (1/2 wider per side). The 70 up will physically fit in the earlier cars but can cause a clearance problem with a wide wheel tire combo but works fine with factory wheels. Mark

jeff if your car is a late sept/oct build you probably got 70 codes even though your parts were built mid to late 69' my pop is full of 70 codes for my09d 69' x66, I too have a 3.31 BS rear on pop, its written as BS0909G, sept ,9th 69' but written as a 70 cuz' car is so late, you may have a three letter block if engine is orig.

I do not have the car this rear came out of. I bought this rear 15 yrs ago and its been lying here in my shop, I'm tired of falling over it, so I would like to sell it. My problem is when I tell someone I have a 69 12-bolt for sale and they ask for the date code and its F180 I never hear back from them.

You sure that zero is not a nine??

The date is definitely F180 and on the other side is CON2, with the # 65 above it in large numbers. This rear has a very nice casting with no pitting there is no mistaking the #'s, they are very bold. What does the CON2 represent?
