This is the drum with slightly larger fins after I modified it and cut off the flange.

The drums from the parts stores are probably closer to the appearance of original HD drums, but I much prefer the ones with the bigger fins which came on the 70s GM cars.
If there was a way to search through warehouse inventories which supplied GM replacement drums, a person might be able to find some drums with the bigger fins, but I have no access to such sources.
Once the drums with the larger fins are installed on the car, all that can be seen is the ends of the fins. Thus, larger fins make a better "showing", as seen below.



Notice the ends of the fins on this drum (replacement drum from parts stores) are not as prominent. I use these on the rear.

Tom, what method did you use to lower the center of the drum to the outer edges, so it was flush across the drum as shown by the wooden ruler? BTW, I could not locate Vol 18 # 4 Winter 2011 of the SACC magazine. Thanks, Al

I'm sorry, I'm not understanding your comment???? These home made HD brakes are on my 56. Is a 56
Corvette not a first generation model?

Tom, I think he might have meant that "He" didn't own a 1st gen. vette judging by his C2 avatar.

I'm with Al Tom. Looks like he's paying you a compliment on a nice upgrade to the C1 Corvette. I take it to mean it's of broad interest to the community.
