I just installed a Hardtop on my Evel Knievel and it turned out really nice.
I want to thank vid1900 on the suggestion on pulling off the plastic that cover the front of the Hardtop so that you can better line up the insert areas.
When I did that on mine I noticed that the clear insert areas on the Hardtop were very hazy and that would have shown thru after install. I spent the extra time to clean all of the clear insert areas on the Hardtop to make sure they were crystal clear. Took a little extra time but well worth the effort. Make sure you check that before you install or you will wish you had.
Cheers!!
