FYI,

I am installing a ZZ4 in my 1985 L69 IROC with T5 manual. I found an article in the Q and A of the latest Chevy High Performance magazine about GMCOPO, a company that has a few NOS ZZ4 Camaro Performance Package PROMs that have been discontinued by GM. They not only have PROMs for the automatic cars, but a special version for the stick cars with a built-in shift light. I ordered the custom 5 speed chip and am scrounging around for the other parts of the Camaro Performance Package. Check it out at:
