Alright as stated in another thread I finnaly got a new bed for my truck (took a while to find one I can afford) however it appears instead of drilling holes to re-use the factory bolts the designer of this bed instead just welded brackets to the frame/bed in the same general locations then cut them off flush with the bottom of the bed when he sold it (not the guy I got it from, hes selling it cause it wont fit the Ford hi-boy he has). So my question to you guys is would it be better to drill the appropriate holes in the flat bed and nut/bolt it on or grind off whats left of the old brackets (not looking forward to it...) and just weld new brackets in? Also going to have to add the appropriate spacers between the frame and bed to keep it level (figuring these are like every other truck Ive worked on where the frame under the bed isnt perfectly level) so what would you guys recommend for those? (seems most the ones around work just use wood but...)
