I've only gone over a few pages, but may I saw wow! That is a truly beautiful frame. And your integration and set up for air ride...bravo! Looks like ill have a late night of reading!
My frame under my Cutlass now only has the outter rear arches reinforced the battery/pump rack from frame rail to frame rail in the trunk tying the frame together in the rear and 1/4" plate reinforced inside my front spring pockets plus rewelded the factory qelds within the spring pockets. When three wheeling I get frame twist (similar to the g body shuffle, but from suspension torque not motor torque.) That's why I'd like to go frame off and wrap the whole thing.
