Probably not at Home Depot, but specialist hardware suppliers (any rack
supplier) will have them, or Tinnerman Palnut themselves. Try a Google
search for "tinnerman" :-) Or see if any local suplus places have any
(look for them still attached to racks).
You'll find that using ordinary nuts and bolts is often very difficult,
because you often can't get your fingers in to hold the nut.

Correct, there are usually three (or four) screws at the front, and the
same at the back. If you've got two parts of the rail, one sliding
over the other, you're just missing the back brackets. If you've got
only one part, fixed to the side of the drive, you have slightly less
than half the rail (you're missing the larger part, with all the ball
bearings, and missing the back bracket). The back brackets are plated
steel channel, about 8" long, that fit over the stationary part of the
rail. The end is bent over into a flange that bolts to the inside of
the rack's vertical member. I dare say you could make something that
would do the job.
