Are you trying to find a drum with the large bolt pattern?

 

[RSM]

I may be wrong but I don't think Mopar ever made a large pattern drum, they changed to disk brakes with the pattern change.

Think you are measuring outside diameter on the brake drum.

2 1/2" x 10" are a standard size.

Try that and search again. Look under B body cars.

Have a look. ^^^

i am building a dana for an a body. making it std width. going to use 11x 2 1/2 inch brakes. i would like to use the smooth drums instead of the finned drums if they make them. yes it will be 5x4 1/2 inch bolt pattern.

You'll probably have to find some good used drums. I believe all the replacement ones are finned. Finned ones are a better design anyway as they cool faster.
