Hi all! Finally a Rat improvement to tell you about. The kids were over at my parents house today so I finally got some car time. I was able to install a new Sparco R100 as the passenger seat and upgraded all of the seatbelts to three point harnesses with inertia reels. The R100 is actually really comfortable and for $300 shipped to my door I could not say no. The Sparco also allows the kids to get in on both sides as it reclines forward with a little lever the kids can actually pull. That makes getting in and out a whole lot easier than when I had the bucket seat as a passenger seat. the Corbeau bucket seat is up for grabs for cheap if anyone wants it.
I have been wanting to do this upgrade for a long time and just haven't gotten around to it. Installing the rear inertia reels was not too difficult. The hardest part was drilling through the package shelf. I think it turned out great and am very comforted to know that the kids no longer have 51 year old lap belts in the back.
