Thank you Hartmut,

    In my case, the aluminum angle is used to 'extend' the mounting lip which is part of the firewall, and thus is not riveted to the firewall.

    I'm not at my home location (I work away from home) so I can't make measurements to compare or contrast the old tank versus the new tank in regards to filler hole location, etc.

    Sigh...I'm learning more ($$) than I really wanted to!!

Regards,
John

 John. I am having serial number 3955In 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. Hartmut

Thanks for that info, Mike.

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.

Regards,
John
