Most of you are aware of the first poster, (see below) and many of you bought one. It's time for the next version, and I need your help. It took a long time to find a D-code vent, but we found one or two (you know who you are, and a new poster will find it's way to you) but in the process of pulling together every style of vent I realized
I'm missing one more: an EH code 1994 vent. Who has one they can shoot a picture of for me? First one gets a free poster when it's done. Anyway, here's the list of all possible vent-codes for those interested. Collect them all! Please pass along any corrections - I'm not sure this is WKC-perfect yet.
