I've always been a fan of these cars as well.
This was my college ride. It began life as a 91 RS 305 5 speed convertible. I found a low mileage 91 1LE TPI 350 t top car and robbed the engine, wiring, and rearend from it. You couldn't get a 350 with a 5 speed. You could also not get a 350 with a convertible. I ended up with a 5.7 TPI 5 speed convertible. The car was a blast and got me into a bit of trouble driving through Volcano National Park from the Hilo side of the Big Island to Kona. I had a Paxton supercharger ready to bolt on it but I sobered up after the brush with the Federal cops in a National Park.
