Someone recently posted the MOOG part number for such a replacement set.
Not sure who originally posted it (might have been me, I don't recall for sure), but I do have a Moog catalog handy. Seems there's 3 different numbers; 8444B for '55-'56, 8457B for '57-Early '58, 8468 for Late '58-'59. Not sure what the exact differences are, the dimensions for the pins themselves is the same for all 3 sets, .8660 x 5.312".
Something I did not mention in my earlier post, I did secure my bushings in the knuckles with Locktite 640.
