YT1 rpo

What exactly does the yt1 rpo mean? the summary in the rpo decoder doesnt make much more sense to me than the one on the rpo sheet itself, which says "dlx 1/4 pan"

From reading the RPO code on the board and what you have posted. I would have to take a WAG and say that it you means that you have beefier doors and quarter panels on your car.

There is a GM RPO code book at the shop that goes to 1991.. I will take a look tomorrow. Hopefully I'll remember.

Not really sure, but I saw on the 84 Z28 Speedster that was mentioned a few days ago, the buildsheet mentioned YT1. It said Custom Dr and Qtr P. I could only assume that you have the custom door and quarter panel trim.
