So I spent Saturday night digging around more in the car, never found the build sheet
Looked everyehere there should be one except for under the gas tank, just no luck so I ordered the invoice and build record through GM Heritage a little bit ago
I pulled the 8 track out, its junk and a Audiovox unit with some kind of bass booster that was crammed in under the console. Probably going to install a modern unit with Bluetooth and Satellite radio
Also got a good pic of the engine stamping, this is the motor she was born with!
She needed new radiator hoses, the upper one was ready to explode and the lower I honestly think was the original since it had tower clamps still on it and pretty much just fell apart when I started to pull it off
