10" would be stock, I believe 10x 2 1/4" in front, 10x 1 3/4" in rear . I have a brand new pair of hoses for front for sale on here. I ordered them for 9" and got the wrong ones, let me know if interested I'll make you a hell of a deal
I might take you up on them...
I was laying in bed ordering parts on Rockauto and was too lazy to go out and measure or get my service manuals out ...lol
The rear drums are going to be hard to find and expensive, rock auto used to have them but I don't see them on there anymore, if your luck you can turn yours and call it good.
