Pat,
I wanted to do the same thing on my Prestige trailer but all the after market setups have U-bolts of some type that attached to the frame. My trailer (and many of the CL trailers) have an extra wide foot plate at the ends of the trailer that wouldn't allow for that type of installation. I called the people in Ohio that made my trailer and they said you would have to have them installed when they built the trailer since they have to cut holes in the foot plates and attach the guideons to the frame. He did send me a picture of at setup that looks pretty good they could make for you (I don't mind emailing it to you) and you install it yourself. It was nice looking, and matched the trailer, but it costs over $360. They do look good though and mainly I wanted them to help me see my trailer when your backing down the ramp to load up.
