Hot Rods 1930 Dodge Floor Install

Hey guys, I've hit a wall now that I'm about to install the floors on my '30 Dodge Sedan. The ch***is is done, the body is sitting on it.

My question is; do I make a subfloor frame that is welded to the ch***is? Or, do I weld 90* channel to the body and build a subframe off that channel?

As you can see in the pics, the body drops over the side of the ch***is. Any help would be greatly appreciated!

 

Here's a pic of the body off the ch***is for reference and one of the ch***is completed.

 

Build the floors to the body, this way you can remove the body complete with floor and have the ch***is bare. Just like the auto industry has for many many years.

If you want you could go the extra mile and build the sub floor to also bolt into the body then the entire body ***embly to bolt onto the frame. I've seen that done a couple times but it's a lot more work and to me isn't worth it.

 

Thanks! Bending the 90* angle steel to fit the coke bottle shape of the body may be a challenge. Definitely limited in skill and tools lol.
