I can't volunteer Nynor's time or help but he is a nice guy and I bet he would be happy to help you.
It would be a fun trip to cross all those states. Just over 2,000 miles is a breeze in a 85 911.
I will bet if you go to the 911 technial board & the OT thread and post about planning a trip like that lots of folks on the board across the country will be happy to meet up with you along the way. You could easily make it a 5 day trip with all the stops along the way to meet up with Pelicans.
If the car gets a good Pre Purchase Inspection you should go for it. I just wish the trip took you closer to Oklahoma.
