I'm sure that with some sweat and elbow grease, you'll have just as nice a ride, or even nicer. All it takes is a will to do it and time (and a few spare bucks :wink: ).
Regarding the calipers: if you can, get them powdercoated in yellow (or whatever colour you like). Much nicer than paint and it'll last much longer. You won't be afraid to scrub them when cleaning since there's no paint to rub off.
When I factory ordered the car in 1982, I didn't want an antenna sticking out of the right front fender (never liked that look) and I didn't care for GM's sound system either (i.e., AM/FM radio). So I order the car with "radio delete" and installed my own system, including the antenna. As you mentioned, it was original and unique since nobody had it that way. During this current makeover, I removed the antenna completely. I'm "Dynamatting" the whole interior and will mount a hidden antenna above the front windshield.
Here's a good view of the antenna location:
