Ward, it's actually even earlier than that. There were four (4) major enhancements that were added starting in the early/mid 6xx numbering sequence:

1. Dropped footboxes
2. Wilwood disc brakes (all four corners)
3. Chrome roll bar
4. Footwell fresh-air vents with manual valves

The 6xx sequence cars were mostly built in the 1999 timeframe. My #747 was built in Feb/Mar of 2000 for comparison and has all of the above enhancements as stock.

Hope this helps,
