That is nice of you to suggest that. When I started the thread, I had a different title for it, one that was vague. I changed it to pertain specifically to this issue so it will be easy to find with the search feature.
I don't know if this issue exists when changing to the 1972 and earlier disc brake setups. If someone were willing to measure their Kelsey Hayes equipped car and post their measurements in the thread, it would help others out.
In short, I measured from the zerk on the left outer tie rod end to the zerk on the right outer tie rod end. Given the variances in tolerances these cars had and with many of them being 50 years of age or older, take my numbers above as a guideline, not a hard number.
Still, I found over 1 1/2" difference between the two setups. I have another drum car and another disc car I could check tomorrow.
