Brake drums won't fit HELP! (pics)

I think you are right. The only thing that concerns me is if plan on using the drums I have that the Yukon axle sticks out 3/8 further than the stock. I don't know what that will cause. If I pay someone to turn them out bigger and then test fit them and find out they don't work for the reason of 3/8 I will be throwing that sucker as far as I can throw it!

I`ve been down the same road as you Mullinax and between brake drums/Yukon axles protruding out further/which led to wheel fitment issues, I ended up Ebaying the axles, drums, backing plates,etc. and had my axles redrilled. I`ll replace them if or when I break them. I used a mid 60`s B-body drum I think, but I had the matching backing plates. You may be able to find a 10 x 2 drum with the larger index hole, but may still have to have it machined if the added 3/8" (by the Yukon axle) doesn`t offset it enough. You can always see if your local auto store has a 10 x 2 and try it for fit. If it doesn`t fit, return it for a refund.
