70 Firebird project, decode the vin and trim tag ?

[ddmrk]

yes the hole support has been replaced sometime in its life if you look at the top of the rad support it has 2 dipresion one on each side it should not have them all 70/72 had a flat top panel here is a picture of a correct one

I thought all Firebirds/Camaro's got 10-bolts beginning in 19701/2. My 71 T/A has a 10-bolt "safe-t-trak" axle. Was the 12 bolt part of the T/A package or an option in 70?

[ddmrk]

all 70 T/A's and Formulas had 12 bolt rear,all 1970 T/A where equiped with a Posi on the othwer hand 1970 Formulas Posi where optional. 71 and up where all 10 bolt

All 70 SS Camaros and Z-28's also got the 12 bolt in 70. After that they went to the 10 bolt.

I knew the early 70 F body cars had the 12 bolt option.
Anyhow, here is what he told me was the trim tag info.
