1992 K1500 Silverado. is there hooks in the bed to tie things down like a motorcycle?

There are no anchor points on the bed floor. The only available tie down points are at the corners of the bed (the stake pockets), so don't go drillin holes in your plastic bed liner just yet.

The easiest thing would be to spread the hooks on the straps a small amount, then pass the hook through the bolt hole in the stake pockets. If you plan on hauling a bike a lot then you would benefit of adding a good anchor point in the floor of the bed.

you should have four squre holes in the corners of the bed those are for tie downs
