I've got these cats off a couple of trucks that I parted out. The first set is off a 1994 and the second off a 1997. I was pretty sure these were original, but the local cat buyer tells me they're not.. Any experts here?

On the 1994 set, there are no markings at all (I'm assuming they were on the heat shield which rusted away).

The 1997 ones have :
"N/TA/99490
93237
0114"
Stamped on the heat shield.

'94 does not lock stock to me...I can pull my OEM's off of the shelf for comparison if needed.
