I think I suggested this to you once before, or maybe it was somebody else ... anyhow, have you tried
Processor-dot-Com yet? I didn't look specifically for those components, but I did check, and typing "Packard Bell" into the search box brought up something just under 18,000 hits from among their associated-vendor for-sale database. If anybody's got what you're looking for, I'll wager its gonna be listed there, or you'll at least be able to track down a vendor who does have it. That outfit is amazing ... just about every computer recycling firm known lists stuff there. Its sorta like the National Parts Finder Service used by auto salvage yards, only for computers and peripherals. The downside is, if you find what you're looking for, you might have to buy a bunch of it ... a lot of whats there is offered only as fixed lots ... but the stuff, particularly older, former-consumer-market stuff, is usually cheap enough to make that practical.
