I am about half done building my own. Should have pics. up in a few days of it finished.
The pad is a headrest from a black Toyota car
I've reshaped the crome rods and have cut brackets something like the ones on babbyhogs.
I still need to drill, weld & paint them.
Mine will bolt to both siderail bolts and allow the crome headrest rods to slide in or be removed.
Give me a few days to do the pics and I will right up the details. So far I have $15 and about two hrs. work in it. I found many headrest will work. It's best to find one with about 7-1/2" to 8" between the rods to clear the seat and line up with the siderails.
