Power stop drum kit

[Desircustoms]

Anyone installed this kit before?

I can't properly fit the drum over the shoes, only thing that seems to help is grinding the bottom ends of the shoe brackets, and the slots on the bottom of the backing plate.

I've triple checked if everything is in the right place, let me know if you see anything wrong. The drum slips in really tight and the adjustment ring is fully screwed in, I don't understand what's wrong.

1st time doing drums and it's a nightmare, but I'm glad I only had to change the steel line that connects to the cylinder, I thought I would have to change more lines, I haven't touched the driver side yet..

Thanks
