If you get the SSBC kit as 65s said, you can use your 10" drum spindles. I bought mine from http://www.performancesuspension.com it is a very complete kit including master cyl. part no. BRAA153 for 10' drums with 4" bolt pattern, and the good thing is if you decide later to go to the 4.5 pattern, the hubs do both pattern and they give you 2 sets of wheel studs.
