10 X 2-1/2” brake drums

So I just assembled the rear brakes on my “modified” 66” Barracuda. As I was getting ready to cut up the cardboard drum boxes, I wondered if anyone cared about the part numbers. So the drums are for 10 X 2-1/2” brakes. Big bolt pattern. (5 x 4.5”).
The heavy duty drums were bought at Advanced Auto as Raybestos part# 2963R

They are finned with a lip but clear the springs with 1-1/2” to spare.
Shoes were Wearever premium part# S333
Bender wheel cylinders 33597 (not sure of inside piston diameter.
Wearever spring kit 7129
Wearever adjuster kit 2528 drivers (left )
Wearever adjuster kit 2529 passenger (right)
Emergency brake cables: Wearever part#BCA 92698 for both sides.

Here is a picture of the drums- shoes and hardware look the same as all- nothing to show. Oh yea! I painted them black. They come sealed in a metal in a slight oily cosmoline like protectant.

I appreciate the info. Sure helps for those drivelines that have been upgraded to later model.

No problem Stephen- those damn stores hire people that don’t really know parts (or cars for that matter) so if you walk in with a part number you are going to at least get what you are looking for.

Thanks for the numbers.

Your welcome Mike. Not nearly as much help as you provide but it’s a start.

I am in Sydney and have just bought a 66 barracuda. It has a 7.25 inch diff. The previous owner has put a CL valiant drum on. The issue is the centre does not line up. Is the drum in the photo the correct drum for a 7.25 inch diff?
