Bronco Info: '83 VIN & title on '93 frame/body w/'95 4.9L & EB paint
The identical base (center) PN only says the parts are used in the same general location on their respective vehicles; for instance, the t/g on a '76 LTD station wagon has nearly the same base PN because it hinges down & has retractable glass, analogous to our t/gs. The first 2 digits of the prefix say one was designed in '88 and the other in '94; the other 2 say both are for fullsize truck bodies. The suffixes (both "A") say that, for each particular prefix & base, this was the first major revision put into production. The base & suffix alone do not say that the parts are identical.
But in fact, they're interchangeable, like all '83-96 Bronco t/gs. I suspect that the '94 A has no holes for carpet, and if you were to find a '94 B, it would. Before '94, there was no carpet, hence the need for a new PN (design revision) in '94. I'd expect a '93 t/g to have the '88 PN, but I can't think of a reason for there to be an '88 revision. Maybe an internal brace changed slightly.
