Finally got time to drive it around today, and I'm happy to say it's a sweetheart - the way I remember them from 40+ years ago.
Cleaned up some details, gave it correct heater & PCV hoses & clamps, a correct AG seal from member 71TA, correct used ballast resistor from my stash.
Still agonizing over wheels - saw one with Vectors - cool against Y2, different, kinda era-correct - but leaning towards TT Ds, if I paint the spokes anthracite instead of the bluish-grey they come in.
So, color me totally stoked. Another reminder to step up & get the best original car you can find; some things are better than money.
It's also a reminder to pay attention & to treat our fellow heads-up members with respect, one of whom told me about the car.
