Complete rally dash frame removal

I'd pull the windshield myself to save on paying a glass guy to do it. Since you're installing a new '68-up gasket, just use a razor blade box cutter and cut the old gasket to get the W/S out. Then you can take your time transferring all the dash components over to the "new" frame. I'd leave the heater-A/C suitcase, freon, coolant, alone unless it needs work for some reason. I'd also leave the console in place to use as a prop for the dash assembly when you go to remove/install it. I like to put a cushion down on it to protect the dash bezel and pad while working on the cables, wiring, hoses, glove box liner etc. Just pull the shifter back into 1st. I'd pull the column out though. I'd also pull the wiper transmission assembly, lube the pivots and linkage, and reseal it.
