1968 10" drum brake hardware kits?

I got the hardware kit from Autozone for 73+ 10" drum cars for my 65 Dart, only ~$8/axle. I had to re-use my pins since earlier cars have narrower shoes (rear only I recall), but the pin springs were the same. I see another poster got a kit with 2 pins lengths in the package. I used the later style adjusters that came in the kit.

As mentioned, rear drums are very hard to find. It appears one could cut the lip off front drums to have them fit. Some have a single lip which would be easier. You might also find correct width drums and drill new bolt holes. For this, Centric lists all dimensions, and you can browse them on rockauto. However, the drums should also have a correct size center register hole, which is harder.
