Have a vibration at between 65-75 mph. Any ideas what this may be?

Start with the simple stuff first. Check your tires and their balancing, then check your U joints and go up from there.

Check tires carefully. If one blows on a Corvette it causes severe body damage.

Default vibration issue resolved

Thanks guys. Had new tires mounted and they were not balanced correctly. Four wheel alignment and high speed spin balance help tremendously.

Vibration is back between 65-75 mph. U-Joints next? Or any other ideas?

when you find out let me know. I have the same vibration on my '86 coupe. I had the local Corvette guru's ( Corvette Masters) look at my car up on the rack and told me the rear u-joints were OK.
