Yes, I believe the Recaro seats were rare on a 1986 Trans Am. They were offered as a separate option, and were not a separate model as some of the earlier 3rdGens were.
That car sounds like it would have been a good candidate for a hi-po engine replacement and then up for some fun on the street.....
