disc brake question

thank you so if i do the small bolt pattern i cant use my 10 inch drum spindles? or would it be easier to go ahead and swap over to the large bolt pattern and look for a new rearend to change to thelarge bolt pattern in the rear?
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.
