Slide out roller assembly

[cvrvr]

Does anyone know where I can find a picture of what the roller assembly on the bottom of a slide out look like. In my case a Tiffin Allegro 30DA, but I will assume that most are very similar.

I removed the bench seats from my dinette area to change over to free a standing style dinette. Sticking up through the floor close to the front edge of the slide are two 1/2 hex head bolts with lock nuts that adjust the height of the rollers underneath. I would like to cut the heads off of the bolts but they are not removable. There is no way to see the underside.

Thanks for any info.
