<VV> Banging the Drum.... Slowly

[movair at aol.com]

Hi Folks!
? Been a while since I've had any question about anything on VV, but I'll lay things out for you more knowledgeable people.
Perhaps someone can help me out.
??I have two, NOS 4 lug brake drums. When layed flat, one is just slightly taller than the other. I had assumed that they were of the 60-63 variety. No cooling fins on these! I have a Parts & Accessories catalog, but it's dated October, 1970. The numbers weren't there. Or, I didn't read it right.
Anyways, here are the numbers. Hopfully someone can tell me what I have and what it fits...
First is box part # 6255561. The part number on the?drum is # 6255548.
The second box part # 6255975. The part number on the drum is # 6256611. It should be noted that # 3830094 has been written on this box?by a previous owner. 
? I no longer have an early Corvair and will be clearing almost all of my early parts. If anyone can help, it would be greatly appreciated! THANKS!!!!!!!
