Re: Disc Brake Upgrade Reference Thread
Most of the discussion in this thread is in regards to the '60-'66's, which do require 2 new holes for the '73-'87 idler arm. The '67-'72 trucks do not require those 2 new holes since the diler arm is the same as the '73-'87's. Which ever year your spindles are, if you use that year of steering linkage, you do not need those adapter sleeves. The '71-'72 spindles use a different ball joint than the '73-'87. I believe it is the uper?
