This is a long shot, but I'm trying to find the owner who sold a 91 RS (or at least was dressed up like one) to the Louisville, KY Pull-A-Part in 2021. It was a V8 (not sure if 305 or 350, didn't spend much time looking), had shorty hooker headers, and was a 5-speed.
I believe it might have been originally an automatic car, because the t-5 that I pulled from it was date coded for 1985 and was a non-world class unit. The trans has blue gasket maker around all the sections, so it's clearly been rebuilt at some point.

I'm just trying to find out any info on the history of that transmission. It's now in my car, and working great, I just like to know the history of things I own.

If by any chance the previous owner is on here, give a shout!
