Slant Fin parts in Ontario

As far as I know when they went out of business they sold their stock off to 2 suppliers. One is a master distributor (sells to wholesale only) and they are basically out of parts. The other who got most of the parts, was parts4heating that sells to anybody. Both are based in the US. The slant fin cast iron product is mostly off the shelf components that don't need to be OEM, if you have their condensing boilers out there it gets a bit tricky, the never actually built condensing equipment they rebadged other manufacturers equipment. Parts4heating has always had stock whenever I look for parts though.
