I am about 6' and find my 73 very comfortable, just like George, even for long trips. These later models had dropped floor pans that created more headroom. Mine has late 90s Corvette seats which are high back and fit/look great, like they were stock. With the seat all the way back, I can't reach the pedals. The only thing you might find uncomfortable after a while is the left leg position which has to be pulled back when not using the clutch. I put a small piece on the wheel well to create a ledge to rest my foot on that doesn't interfere with getting to the clutch pedal. You can stretch your left leg straight by putting your foot behind the clutch pedal but I don't recommend it for safety.
