John. I am having serial number 3955 . In the nineties the header tank had been replaced with a new one from Univair. In the process they riveted the aluminum angle you are mentioning to the firewall. The filler neck hole had been shifted as well; in the stainless covering and the cowling. The riveted aluminum angle is fitted so that I can not remove the tank without de-riveting the angle. The control column just passes 1/2 an inch below the tank.
I would check the hole for the filler neck in the stainless covering and make room there. Later you will have to add a doublers ring to the top cowl to cover the old hole.

My coupe is SN 3608, a 1946 415-C model (thanks to Ed Burkhead for reminding me to post that info) so I guess I shouldn't have the same problem you had. Back to square one...groan.
