this is the response i got by emailing mar-k:
----------------------------------
We have a complete hardware kit which includes the bed-to-frame bolts (which mount your wood to the truck frame), the bed strip bolts (some of which bolt through your cross sills), and the angle strip bolts (which bolt the angle strips to the edge boards. These would be all the bolts that attach the bed to the truck in any way. The part numbers are:
Polished Stainless steel:
#110360 $92.00
Unpolished Stainless Steel:
#110361 $72.00
Zinc-plated Steel:
#110362 $42.00
These kits are all for standard angles, bed strips, and bedwood with standard mounting holes (square shoulder carriage bolts), but we also have kits with ribbed neck bolts, etc.

hope this comes in handy to someone in the future
