One thing is that truck bolt patterns are different than car bolt pattern. I believe that your rear should be a six bolt if its a half ton truck?? I do have a question for you though. I have a 86 C10 front end on my truck with the stock 69 front crossmember. I cant seem to find a set of headers to work due to them hitting the rear of bottom A-arm at the collector. Any advice on this since you are using a 73 front end. Not much difference in what im running I believe?? Thanks!
