Is it possible or desirable to use the earlier linkage on the later cars? I could never figure out if this was a cost-cutting measure or a product-improvement measure.
The 68 thru 72 linkage I have on hand for my 67. 67 and earlier have bronze bushings everywhere. Only point of failure is the special pitman arm bushing. That type can get noisy er with age. Plastic is quieter and serves as a point of failure.
