What I'm really after is the black plastic carrier the PROM chip installs into (which is the item on the LEFT in the picture above). Both the PROM chip and the carrier get removed from the ECM at the same time, and it can be very difficult to separate the PROM chip from the carrier without damaging either component. I actually have little use for the factory PROM chips themselves, as it is the plastic carriers I need. However, since it is difficult to separate these two items from each other, I would prefer to just buy both still together as it would come out of the ECM so you don't need to worry about separating them yourself (and risk damaging the carrier).
I would like to purchase multiple quantities of these carriers at once, otherwise shipping will be a greater expense. So if you have 3 or more proms and carriers you want to sell, let me know and we'll negotiate a price.
NOTE: 87-88 Fiero 2.5L Iron Duke ECMs use a larger PROM (28-pin) chip and carrier which I do NOT need. I need the type primarily used in the 85-88 Fiero 2.8 ECMs (and other GM ECMs of this era) - which are 24-pin.
