Okay here goes; I have a 69 dart that I am changing from sbp drum to lbp disc. I recently purchased the 73-76 parts needed to do the swap, upper control arms, spindle, bracket and the misc odds and ends. After doing the research, I am going with the wilwood kit. Now my question, the cost is the same for a kit that bolts on to my new stuff and a kit that bolts on to my existing drum brake spindles. So should I get the kit for the drum spindles and sell the conversion parts, or get the kit for 73-76 and use the later spindle and control arm. While i'm not rich, cost is not a factor in this decision and I will be getting a front suspension rebuild kit. Are the later model parts stronger? Thanks in advance for any suggestions.
