Thanks for your votes of confidents guys! First order of business was to drop it a bit in the back. I was a bit nervous about sawing the frame in half so I pulled a used frame out of the stash that came from a MPC flip nose 57 Chevy (they share the same chassis and suspension!)
Once I added a block and glued it back together the front needed a little lowering to get the body to sit level. I was able to cut the front springs off the chassis and reduce the height of the spring blocks. Here's a shot of the stock frame in the back with the modified frame in front.
