Boy o boy would I do a ton of little things while I had it in this position,,,,like make a better shield for the mode position switch and some other connections....FOR SURE DO THE THERMOSTAT and replace it with a failsafe one and never think about it again.....water pump & timing belt...intake manifold gasket...on and on. You get the idea.
I've no idea what your setup is, but getting the body up and off this car is a piece of cake. It's no more difficult than lifting a pickup off it's frame...in fact it's EXACTLY like lifting a pickup cab up....An easy one (maybe two) day deal.
I'd get polyurethane bushings everywhere while you're in there too...a ton of things....you get to re-engineer a bunch of stuff
