1929 coupe subrail salvage...

[Martinbuilt]

Hi.
I'm new to this forum, and just starting on a '29 business/sport coupe.
The rear half of the body is pretty solid, the ugliest part is behind the cross-member.
The subrails need a bunch of work, but i think i could save them with a couple good photos. I'd also be interested to know if they are dead flat, or have any contour.
Meaning, a new set would or would not lay flat on the ground.
As you can see in this photo, mine are happy to lay flat on the ground...
