Robert,
I like it even has a v spreader bar but in binder you could call it a cattle bar.
Just one pointer on the buggy springs. They like to move around and work well being trapped in the upper mount. An inverted "u" that captures the leaf sides. If you don't trap then they will shift and bind the shackles. On your setup shoot for a 45 degree shackle angle after being fully loaded with the tin work and engine. That makes them the most stable. Are you going to run a front or rear panhard bar? I see coil overs on the rear and think a panhard bar mount on the pass side rear.
