I'm pretty sure Bill is correct on this, -and what Mike is suggesting is correct however confusing because the parts books do say to order an AA-17754-B if you need a service replacement for an A-17750-B. This is however, not suggesting that the AA and A front bumper arm are the same. What it is saying is for a replacement, order the one for the AA. This was likely a cost savings method for the depots to only stock one bumper arm, -and the AA length arm would fit on either the pass. vehicle or the commercial veh. whereas not visa-versa.

Also, understand that the MAFFI database is a HUGE asset to the hobby however not all information that is at the archives has been listed in the MAFFI database. I have found many prints for items like fasteners and other sub-component items at the archives that have not yet been listed on the MAFFI site. Therefore don't assume that just because something is listed (-or not listed) that it is the total story.
