were disc brakes a required option on the gt or mach 1?

found a car with GT on the buck tag, but with drums all around

looks like a mach interior, but no door tag to verify 63c...

 

Im not sure on disc with a mach1 i know a gt had them but just remember its a older used car who knows whats really been done to it.

 

I believe Mach's had all the GT stuff automatically and were stamped with the GT on the buck tags, at least mine is. Mach's or GT's did not come standard with disc brakes, it was an option. I have seen many Mach's with drums front and back, even some 428SCJ cars.

 

69 GTs are rare compared to Mach1s. Drums were standard.
What is the engine code on the VIN?

Nice car chillininnh, how many hours on the restore?

 

H, 351 W..

 

Without the body code, who knows?
63A = sportsroof, any engine
63C = Mach1, H or bigger
? = GT?, ?engine?
