63-65 Drum Brake Question

[Subfixer]

It's about time to R&R the brakes on the '64. When I bought the car, I noticed that the left front drum looked like an original (old & rusty) and the right front drum looks new (Bubba work for sure). Both drums are finned and only the left drum has the spring wrapped around it. Here's where my problem starts..... After searching all the vendors I can find, I can't seem to find replacement finned drums (looking for 2 so they at least start wearing evenly). I can only find drums with a smooth surface.

2 Questions: What drums should be on the car, and if finned, where do I find them?

No finned drums unless Z06 or J56 (even Standard J56 didn´t have fins....)

Guess your car should have simple and normal drums....no fins.

Looks like another "Bubba Mod". I'll get the correct non-finned drums. Thanks for the replies.
