If they came from an Fbody, then they are 99-02. The reason that I say "if", is that the "411" PCM came in s10's,trucks,vette's and fbodys. I'm not sure what the "09354896" designates, but you might try calling a dealer.

Actually, 99-02 are the same in the Fbodys....just the tuning is different. 98 is an undesirable year, and I believe is NOT a "411" pcm. 98 has less internal memory/tunable parameters. 99-02 is what you're looking for, generally-speaking.

All three of them could be 99-02 PCM's, the third one for sure....The 411 PCM came out in 01 to 02 on F-bodys, and started in 01 and up for trucks. It is more sought after because it has 512meg of ram, can be flashed to run several Operating systems for cars and trucks, and also multi bar map systems....

Look on the PCM's and see what colors are written on the side of the PCM, red and blue is usually F-body, red and green is usually truck, van, GTO etc.....

I think those dates are close, somebody correct me if I'm wrong...
