Wow Dr., looking at the options sheet that was my first G-body, except for color (my Calais was lite blue w/ blue interior) and it had the rallye gauges and windshield antenna. Funny thing was it had the 4.3L (260) V8 but had a TH350. It was 10 years old when I bought it but it was in great shape!!
Bernhard, I found a set of the N78s a couple years ago on eBay, got them for $280 (including shipping). They did not come with the lugs but the paint and finish are pretty decent.
