Your first car upgrades? (Electrical/Mechanical)

Gotta laugh... first thing on my last acquisition was to tear OFF the MSD and reinstall the stock-type electronic ignition- 1000% better, for whatever reason that particular MSD would not run worth a hoot no matter what I did with it. Not hatin', just sayin'. Then got some vacuum leaks taken care of, sorted out the butchered kickdown linkage, and tuned the carb. Cleaned up all the bulkhead connections. And the usual tune up, of course. Then full brake inspection and fluid change.
