Sorry, yes it is a 1950 3600.
Thanks for the clarification that it should be basically flat. Mine was bent down in the middle and pretty wavy but nothing like the one that Kevin restored - great work.
Is the flange intended to be flared out in the area of the two inner mounting brackets? I am thinking yes in part because the brackets do not appear to be relocated and require the flange to flare around them but if needed I could remove the inner brackets, repair the flange, and reattach the brackets.
