I love what you have done saving this rig...being a past old Fla resident caught my eye about your thread, and I read the entire thing... I too have saved many old rigs like yours, and alway go thru them from bumper to bumper restoring and repairing PO nightmares and wiring rats nests...
One thing that did concern me is the use of "copper tubing" for brake lines... Im hoping you are talking about ni-copper lines, and not " plumbing grade" copper tube.
Plumbing grade tube should never be used for brake lines where hydraulic pressures can easily exceed 1000 psi...I would hate to hear of a complete brake failure if a line split open and your family were hurt in an accident...


just an FYI...and if you used nicopper...carry on..
