Last year I purchased some plastic racing seats to put into Gus. However, I was never very happy with them. I never felt like I fit as well in them as I did in the seats I put into my first jeep. After searching for months for seats, I finally discovered a pair of beat up seats exactly like what I used to own on Craigslist for only $20.
To get them to meet my my needs, I needed to repair the fiberglass (extensive holes and cracks) and then drill holes for side belts and shoulder belts.
