Look on the
Hurst/Olds Club of America websiteand get hold of Karl Sarpolis ('68 H/O Advisor). He has the list of VIN's and can help you out. I am sure that he wants to learn about this car and its condition. PM me with your phone number and I will give you a call.
Another '68 H/O race car that is going back together (as chronicled by a thread here) is the Russ Dunmire race car. It had already had a top notch resto done, but managed to imitate a barrel and rolled. I could not believe how good it is coming out of that wreck!
