Take the tow bar off, they're ugly and the electrics are now an MOT test point, if you don't need it get rid.
Love the electric windows, I used all the mechanisms and switch from an early 216 Vitesse, put the switches in the front spreaker grill. Any plans to electrify the rear windows ?
In terms of anti-pinch that's a pretty modern invention, most pre 90's cars don't have it, my 820 doesn't, and the 216 I used for my conversion didn't. Later 800's had it but it complicates the system and makes it unreliable, I'd stick to the simple up down switch setup.
