maybe some others will chime in on that, but i have never seen or heard of a 78 with factory rear disc... but could be wrong or some special order from a GM exec late in 78...

The hex caps were definitely 79-81.

After reading a bunch, I think you're right. Somehow disc brakes worked their way under this car, which I dont mind necessarily. I do have a date code correct 78 axle with drums I could put under it, but we'll see.

I believe it has the original master and proportion valve, which I would imagine make the rear discs unpredictable under use. It'll be getting all new everything, so I can just keep the discs and use the correct setup for them.

I'll grab more pics of the car tomorrow for you guys. It currently has a Chevy Q-jet on it, but I just ordered Cliffs rebuild kit for a 77 Pontiac Q-jet I'll use on this car.
