Easiest way is to check with Mar-K (or other vendors). They sell a bolt kit that takes care of the floor, and may also sell the others. IIRC, the front panel to bedside bolts and front panel to cross-sill bolts are 1/4-20 (probably 3/4" or 1/2" long with a flat washer and lock washer under the nut. I believe the rear corners are also 1/4-20, but they may be 5/16. You can check the drilled hole sizes and use the largest that will fit thru the hole. They are all hex head bolts.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
