Cant stop!!!

I have a 1969 dodge dart custom with 9" drum brakes and I want to convert it to disc brakes... I would like to find a complete kit at a reasonable price. I would like to changd the bolt pattern as well but I have no idea what to do with the rearend to make it match the front.. I'm thinkin a 5 on 4.5 pattern.. Any suggestions?:roll:
