I have had microfiche for 1990 to 1995 U body for a while, but only just managed to get a reader for it. Looked up the PCM mounting, and they are very different for 92-93 vs 94-95.
The bracket is a different design there seems to be a plate bolted at the bottom as well as bolts at the top.
I don't have the microfiche converted to digital, so here is a photo of the assembly, hope you can make it out
