Hey Chopper,

I just ordered those rear door screws from St Charles Isuzu. If you call and ask for Merlin, he's well versed in those specific parts. The screws are sold individually (something like $3 or $4 each) and then the plastic receptacles are sold in a package of 4 ($4.75 or so for all 4). Be sure to ask for the specific color screw! I ordered red, but they also come in black and gray.

You could buy a replacement set of four screws with four receptacles for around $20, shipped free!!!! Always nice to have spares around.

Oh, and a few people have already done your insert-dowel-into-screw mod. It IS a cheap way to prevent breakage.
