Thanks all.

I suspect the clearance data was the same for 68 and is a good reference nonetheless.

I have the correct space saver tire, jack and accessories in the trunk - no more or less than what should be there. I also don't have air shocks but I think the problem is the shocks (the response when I hit a bump or pothole supports this). I will give it the bounce test on the weekend and let you know.

Thanks,
