I used the stock 240 tank, and welded a sump to it. I cut out the spare tub, centered the tank, made new mounts, and straps. To connect to the stock filler, I used a galvinized 90 degree exhaust pipe ( I think 2 1/4" ) shoved one side up the stock rubber by the quarter panel, hose clamped it on. On the other side I bought some 2 1/4" rubber fuel line (made for connecting tanks to filler necks) clamped it over the exhaust pipe, and the other side connected to the tank. I only needed about 8 " piece of fuel line.
