c20 rear disc conversion rotors

[ullose272]

im in the planning stages of my c20, was wondering if anyone knew if the slide off rotors off something like a H@ hummer or 2500hd would slide on in place of the drums on my 86 c20 axle? it is a semi float axle and the bolt pattern is the same.

after doing a little research it looks like H2 rotors may work, looks like the center bore on the c20 drum is 4.60 and h2 center bore is 4.63.
