Brake drums

[hairball]

Hi all
My original brake drums on my 65 C10 had a cutout in the drum for a brake spoon to adjust the brakes. I first ordered Raybestos drums and there was a place to knockout but damaged the drum while trying to punch it out. I then ordered Bendix drums and there is no sign of a knock out plug. Both of these brands were made in China. I realize that I can just pull the drum off for adjustment but what if the brakes became too tight and not being able to back off the adjuster to remove the drum? Is there a brand out there that matches the original drum with the adjustment hole in the drum? Thanks and hope everyone is staying safe.

Easiest way is to make a slot in the backing plate at the bottom for adjustment access.
Use a plug like this to cover the slot.
Just an example.
Parts stores have them.

I usually see the cutouts in the backing plate, not the drums.

I bought mine from Advance Auto and it has the adjustment hole.

I had the same issue with some I got from Rockauto. I drilled four holes side by side and hacked and filed the flat area.

I was surprised to see that my original factory drums had the holes in them as I have always seen them in the backing plate. But my backing plates do not have a hole. (1966 C10 base all 4 corners).

I would recommend putting holes in the backing plate if possible. IMHO the tire should be on the vehicle when you adjust the brakes.

In any event put a hole somewhere. You can't get a good adjustment with the drum off.
