72 Demon 440 Conversion Help

Seriously, get a V8 pitman arm and compare it, in person. You may have the correct 72 era pitman arm, but I've seen cases where the Slant 6 car's, which have a different pitman arm, can cause issues.
I was thinking of that. I should just replace the pitman and the idler arm and see what happens. I can always send them back if they are the same. Not sure what year the manual steering box is from and it had the pitman arm on it. Probably from a different year range.
