I don't see anything that will work for my system on SBO or Hamilton. There are some parts on the Moyer Marine site which isn't surprising since they are the Atomic 4 specialists. I'm trying to source parts in Canada since the shipping, duty and exchange will double the cost if I buy in the US. I'll probably buy the flange from Moyer and piece together the rest from iron plumbing bits. They do have a nice stainless water lift exhaust that looks like it could fit nicely.
