Re: 2WD C10 Modern/Performance Alignments

A few points to ponder:

I looked up that 6147 number and found that several manufacturers use it. One being Moog in their Problem Solver line. Could it be that any cross shaft with the number 6147 has the index drilled at 1.5"? I think its completely plausible.

Crakajax crunched the numbers and found that for every .25" of movement a gain of 1.4 degrees is gained. So as an example:

My truck currently is 2.7 on the left side. Just replacing the shaft with the 6147 number should net me 4.1 degrees which isn't bad. If I drill the index at 1 7/8" (1/8" equals .7) my caster would be at 6.2 and at the 2" mark my caster would be at 6.9 degrees.
