I'm looking for a OEM PROM for an 87 TPI IROC-Z. I found these 2 PROMS and they look the same but are they significantly different?

Re: Need help fellow members. Are these 2 PROMS the same?
I believe the ABWT is a revised ABWN code. They are obviously for an auto trans 350 car with 3:27 gears. If you have that gear ratio, either of those PROM's should work for you.
