Thanks for the generous offer Barnfind, i have to be honest and say that my own project(not the T25, an early bay Westy)is some way from needing a gas tank but an underbody tank is the way I'm thinking. I've got my hands on a rollover jig and hope to have the van turned in the next couple of weeks and can get my fixtures etc in place for the tank. If you're happy to let it go and Riggsi is ok with it I will arrange collection. Thanks again. Paddy.
