Hi, I see NOS 224 flashers for sale from time to time on eBay. This one has a yellow can: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem <http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=250426441279> &item=250426441279 I don't believe this style of can was in use when Corvairs were new. The cans were aluminum colored, right? Thanks.
