I don't see any bass pickguards available at their eBay store, but these guys do sell precision bodies online....so it's worth a shot (send them a mail through eBay?):

I bought that same strat pickguard from them many years ago and it was nice quality, although it kinda warped from the copper tape I put on the back of it. If you do find one, make sure you spray some nice hardcoats on it to stabilize it and, of course, bring out the grain more.

(might want to consider a shielding plate instead of tape, too).
