I've got a set in my 1980 Scout II. My Dad and I adapted them to the Scout II bases and sliders. What we ended up with is a seat that is way too tall. I've got an adjustable steering column, so I was able to raise the wheel all the way and still drive the truck, but if you don't you May have trouble getting your legs between the wheel and the seat bottom. Regardless the seats are still a bit too high to be comfortable. When I get my Scout up and running again I'll be either getting the corbeau sliders or having new bases tube bases made.
Also, the black fabric on my seats has faded to a dark dark blue. Before I bought them I read some reviews saying the black cloth had faded, but I read some other stuff saying they had changed their dye and the fade issue was gone. Well with my seat bought about 6 years ago, they are now faded. I still love the seats and knew it maybe a problem when I bought them.
