Any seat from an MR2, supra, celica, or such-coup type car will fit with minimal issues. Also seats from honda hatch backs will fit really well too. I say these type of seats b/c the coupes all have the folding back seats so you can access the rear x-cab easy. Best seats if you can find them would be some from a camry coupe. They slid back and forth and also had electronic up/down/back/forth and had adjustable lumbar.

I still have my 60/40 bench. I would much prefer a 40/40/20 type like the old F series had or perhaps buckets-but then I remember why I like a bench-3 people up front if I want, folding armrest that actually feels like it belongs, etc. Upside if I did go buckets it build or modify a stock type console and give myself some damn cup holders!
