I'm looking for the part number to ask for when ordering a blank EPROM for a '90 chevy truck. This would just be for the EPROM, itself and not the case it fits into. I've ordered them before, but it has been a few years and I do not have the part number or dealer I used. There was a place in Wisconsin, if I remember right, where I made my last purchase. Can someone help me with this? In particular, if someone happens to know which one to order for a diesel, this would be helpful, as well (I understand the two chips have different mapping characteristics).
Thanks!
