Fitting gas tank

[Lee Mitch]

Hey all. I have heard and read about the woes of fitting gas tanks back into the cowl. I am finally there on my ground-up restoration of my '30 Briggs fordor. After much cursing and scratching my newly painted tank, does anyone have any tips to refresh my memory? The welting is so tight that it doesn't allow the tank to fit or to move the lacing into position. From a novice in Model A terms, thank you very much!
