I'm trying to track down manifolds for my cat 30. I tried emailing catman but have had no response. Also need a cylinder jug.
I found a jug but no luck on the manifolds yet.
Worst case scenario, do as Diesel35 did on his Sixty - some ingenuity and pipe fittings make manifolds, at least till you find what you are looking for. Wasn't the fellow in the UK going to cast some new ones? - cts
