John, Last spring I spent a number of miserable hours on my back trying to fit a tank from Univair. What isn't discussed is that some where in the 800 + serial numbers the cowl dimensions changed. The top of the cowl was widened and the fuel filler neck was moved forward an inch or so. A current production tank just will not fit under an old cowl. My thinking is that some where in the past your cowl was changed. Univair, with some prodding, took my tank back for a refund. Unfortunately I cut a new hole in the cowl for the neck and then learned about making doublers to patch the hole after I gave up on the new tank found the correct tank on the swap pages. That is my experience. Mike @C35
