If you cab grab a pic that would be awesome. Never thought of using sled hifax for bunk slidersI used some 2 1/4 hex wood screws. The nice kind that don't split the wood. I also put snowmobile hi fax on top of the 2x4. It makes it very easy to slide off onto the hitch hauler. I also put a shelf on the bottom that comes in pretty handy. If I have time I'll try to snap a picture.
Post a photo, will ya?built mine recently, great kit to have in the shop!
