I painted the crossmember and bolted it up tonight. I then started tackling the floor and grew frustrated and walked away.
I was going to make a cross brace over the top of the trans out of 1/2" bar stock and combine 2 of those with some 1/8"x2" steel flat stock. But I think I might go out and try and find some 2"x1/2"x1/8" U channel.
