I want to replace the trunk lock cylinder because I lost the key and the lock wasn't working very well to being with since they tried to break into the trunk and they pretty much destroyed the lock.
But the trunk lock cylinder that's sold by the Fiero Store as well as RockAuto, are for the notchbacks and don't fit...

Yes, those are for notchbacks, they don't fit fastbacks.
This is the correct one: https://www.ebay.com/itm/304968230480
But they don't mention a part number and I don't think these really cost $85...

Cliff, I thought the lock cylinder was the same and the only difference was the length of the rod between the cylinder and latch. Of course, 88's also used a different key blank than earlier years.

Yes, I had seen that one and it looks like it will fit but he asks $40 shipping (for something that fits an envelope).
