SBP to BBP?

Hey all. I know this question gets asked and answered all the time. But I am having trouble finding the posrt from the past.
Question is, what are the vehicles that I can exchange with my car? I have a 72 Swinger and I'm wanting to convert to BBP. I have the KH disk brakes now. I will be going to the junk yards this afternoon to locate a donor but not sure what will work. I did have a 79 Valare scouted. I went Saturday to strip the brakes but found the car was gone. When I asked about it they told me the car was crushed last week. Just my luck, i get the money saved up and they got rid of the car. So if I knew what other cars I can look for it would ge of great help. I just can't remember the site that would tell me all the exchangeable cars. Thanks for any and all help.
