Art, that's part of the problem. The Tacoma's bed rail has only 5 (I think) spots where their proprietary cleats will securely fasten. The rail itself runs the length of the bed, however.
Richlacal, I'll have to swing by Home Depot today and eyeball those parts. Thanks.
Old school is that it is a truck and a service vehicle and they break out the drill and a half-dozen sets of eye bolts, standard and fender washers for both sides, and nuts to fit. If they were pedantic they might squirt a bit of silicone under the washers, snug them up just enough to squeeze out the air and come back after the silicone was dry and torque them. With a pad of silicone underneath they are vibration resistant and won't cause the body panel to rust out. You mount them at all strategic locations.
Cleats are more my style and the nylon ones are light, cheap, and just about strong enough for any reasonable load. But you still need to through-bolt and use a wide and thick backing plate or large-diameter washers stacked to keep them from flexing.
Kind of ruins the resale value, at least for the wider population who don't know what a truck is about, but traditionally you keep a truck until the wheels fall off.
