Crankcase ventilation filter cb4

I have found a source ( a 2nd source) for the crankcase filter element found on 63-74 V6 engines. the AC Delco p/n CB4 is available on Ebay in this listing eBay item number:236069458319, and it looks like he has a quantity of these rare filters. Wix 42718/napa 2718/Baldwin pa1622 are equivalent.
