I think you are good to go. I happen to have my skid out to clean it up and repaint part of it
There is a definite gap all along the bottom of the rail, supported by the wheels.
Never mind the blue rear wheel.....I did that MANY years ago when a lot of the new sleds were coming out with colored idler wheels. I remember having a can of Chevy blue engine enamel on the shelf....left over from some project or another.
It has held up pretty well over the years, but I think I'm going to return to the stock, black look now, since I want to keep the Invader mostly a nice, stock survivor.
Kinda hate to remove the blue paint.....best performance modification I ever made.....added at least 10 mph to the top speed.
