I haven’t welded those rear frame connections yet. I keep changing my mind on how I want to do this.
Also there is some additional tubing that needs to be worked onto this connection, where I reinforce the frame at the door sills.
I decided that I really needed to work out the sub frame connections and brace the crossmembers. I have some odd stamped channels & light tubing that will do the job quite nicely.
There you can see how the heavy steel brackets will bridge from the reinforced crossmember to the edge reinforcement channel on the back of the floor pan. (Where are the red magnets are.)
Those landing pads need some big bolt holes in them and I don’t know exactly where they’re going to be. I know approximately, based on what the pan was like before I reshaped it and Welded up all the holes.
But I think I’m going to put oversized holes in them on the drill press before they are welded in, and then I will use big flange nuts.
The rear subframe rails will each get some sort of a reinforcement shoe on the on the forward end, which attaches with the flange nuts.
