[torontocbm] Spare PLA chips?

While attempting to fix a C64 motherboard I mistakenly swapped PLA's into the 
SID socket... guess what?... PLA's don't like 12V :-(

A long shot, but does anyone have any spare PLA chips? They don't seem to show 
up on eBay very often these days...

I know I can get work-alike replacements for about $10 each but I'd like to try 
to find real chips first if possible.
