Great to see pics of 'work in progress', something I enjoy immensely anytime.
Not trying to nitpick but were the original floors of the design the denter is fabricating?? The ribs beneath the seats are perpendicular to the cars axis while what he has fabricated are parallel. I may be wrong as I know absolutely nothing about Yankee metal.
It may be worthwhile doing an as correct as possible resto as you are in any case spending a big amount on the job anyway.
I hope my comments and observations do not offend you in any way. Just my 2 cents.
Best regards.
