I actually have this on my list to look at when Benson re-opens however in the interim there appears to have been an A-17754-A, A-17754-B, A-17754-C, A-17754-D, and A-17754-DR for the 28/29. Then in the early (Feb 1931) PPL, it references ordering a AA-17754-B. Looking on each of those prints specifically for application may be the key to determining whether they were the same as Pass chassis. The revisions must have been fairly significant to assign a new Suffix to the root number. Any theories why so many changes??

Sorry, I don't have any bumper arm engineering drawings. I did compare my Feb. 1930 AA front bumper arms to 1928-1929 front bumper arms (on both A-chassis and AA-chassis). The Feb. 1930 AA front bumper arms were not the same and were as pictured above.
I just looked at A-chassis parts in my Oct. 30 1930 PPL - for 1928-1929 RH/LH front bumper arms it notes to order AA-17754-B/55-B. My guess is that Ford just didn't make the original A-chassis arm by that date. It seems the PPL should have specified ordering both AA-17754-B/55-B (not just one side).
