Diaclone feet.

I have slowly been collecting the G1 Trainbots, I've got 1 late era G1 boxed and complete, 2 Diaclone boxed and complete and a third Diaclone which is boxed and nearly complete. The nearly complete one is missing only 2 things, the 3 green couplings (not too fussed about) and the Diaclone man's feet.
Does anybody know a reliable place I can buy a couple of replacement blocks for his feet, or a junker Diaclone man who's feet I can use?
