Default GM EGR Block Off Plates

Doesn't GM have EGR Block off plates for the intake?? If so, does anyone have the part numbers for them? I think I remember reading somewhere they were on 96 LT4 Vettes.....need them within the next week, and I live 2 minutes from SDPC, and would rather get them from there, instead of online....unless it would be quicker/cheaper ordering them online.

There is only one plate made by GM #10054880, because that is all that is needed for the intake manifold. It covers the two holes on the drivers side where the EGR valve mounts. You're still going to need one for the Pacesetters

Sorry to burst any bubbles but I work for a chevy dealership and GM has discontinued the LT4 block off plates, I got mine from UMI. FWIW, I also had to mod one of them.

I bought my EGR plate from Thunder Racing. On my Vette I had two holes on the back of the intake manifold. I used the block off plate on one. If I remember correctly the plate I ordered was too large to mount where the other hole was. I had only ordered one anyway. I cut the pipe out of the factory plate and used a flattened nickle to fill the hole.
