Anyone have any info on this?

 

After doing some research, here is what I have found. According to original Pontiac sales brochures, there was supposed to be a limited run of only 1500 350 Formulas for 87. Someone had contacted Pontiac and was told that a total of 2384 were produced in 87. I am going to contact the Pontiac historical services and see what they can tell me, but I'd guess it's safe to say that between 1500-2384 is a good estimate.
