Remco Frankie joint pins? Help!

[Saroyan]

I just won this auction for a Remco Frankenstein with busted legs:

eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices (http://www.ebay.com/itm/390394343162?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649#ht_500wt_1076)

Can someone tell me what a good replacement pin is to use for the knees and hips?
