Hey Mello,
Look at 311s.org and you will get everything you ever wanted to know and more about the Lady's! A 67.5 2000 is the holy grail. There is a real nice 69 2000 for sale in The Dalles right now for 4K. If I wasn't already working on my 2000, this one would already be in my driveway. 68-70's have the taller wind shields and also have a better steering box set up. The low windshield cars have the flat dashes with cooler gauges. I like the side markers on the 69's and will set up my SR car with those. It is all just personal preference for the most part.
