A-body vs fmj spindle for handling?

YY1 said

I believe E body spindles are the same as 73 and up A, are they not?

FMJ is the same as 73 and up B, again IIRC.

The whole point on the FMJ to me was-

I've seen exactly two 73 and up A body cars at the U pull yards since the late 1990's.
(I go to six yards in three counties every year if not more frequently)

I've seen more than two dozen F and M body cars in that same time frame (and two J's).
With a few late 75 and up B cars showing up as well.

If the handling differences are negligible, then the supply difference becomes a non-issue.

E-berg ragged the FMJ part pretty hard in his article.

BigBlockDart refuted it with tangible evidence, and I believe them.

Case closed for me.

B and E body spindles are the same 70-72 and 73-74. So E and FMJ spindles are the same height, or about 3/8” taller than A-body spindles. I didn’t check the SAI to know if that changes with the later B and FMJ spindles compared to the E’s, but the height is the same.

The A-body spindles were the unique ones, just like they were the only line to get the 5x4” bolt pattern, the small ball joints, etc.

The big block dart article is a re-print of the one that was written by Bill Reilly and originally appeared in Mopar Muscle and is now hosted by Hot Rod and linked above. E-berg ragged on the FMJ spindles but he never did any actual testing or analysis. He was completely wrong, and he’s never admitted as much despite having multiple opportunities to do so. When he wrote up “part 2” recently that covered that god-awful Liberty rear brake conversion he even threw in a little side note patting himself on the back for the original article, with no mention that his speculation on the FMJ spindles was incorrect.
