Here's what the '36 frame horns looked like originally. Not very pretty for a fenderless car.
There's a bunch of that X member in the middle that's going to need to be reworked! Not sure that trans tunnel will work and allow servicing the 4 speed either, as it might require pulling the engine/trans if it's trapped in there. So we may end up removing the whole X member and replacing it with round tube framework to make it cleaner, and easier to build around.
