SBP to BBP?

thanks guys. Yes I have an 8 3/4 rear BBP out of a 65ish belvdre(sp). i do like the kh 4 piston brakes and I know they will work for the driving i will do, but i would like to have the same bolt pattern for the front and rear. I guess i could just buy some adapters and call it good. The rotors and pads look new on the kh setup. I wentbeen going to the YARDS around here and it seams like there is a guy going around and buying all the dodges he can get his hands on, even the small back yard stock pile of cars. damn him. So i am thinking i will be able to find the parts i need on ebay and will save on shipping huh? oh well my luck. thanks guys
