randy my header bar had a high density foam glued to it . I think the home depot stuff will work.Another option would be the 2 faced tape used by body shops to attach name plates etc. I used it as the seperation between my wing protector and my wings. It has some cushion and stays put. the stuff i have is only 1/2 inch not sure if you gan get it in other widths.
thanks ron, I was thinking of going to the hardware store tomarrow and getting the high density foam stuff and just laying 2 strips down. One in tthe front and one in the back. I think that will work fine too.
