Ok so I've figured out where to get just about all the parts for assembling my short fleetside bed, but cannot find the screws to attach the panels together (wheeltub to beside, wheeltub to bed, etc). the only ones i could find were the ones for the bed front to bedsides, and the rear cross sill. if anyone could let me know where to get these id really appreciate it. thanks.

oh and also can someone PLEASE tell me how many standard cross sills to order? i know i need one reinforcement strip, one rear cross sill, and then i dont know if i need 2 or 3 standard cross sills like these: http://www.mar-k.com/catalog/catalog.asp?TruckCode=19631963CW-90
