I appreciate all of the positive comments. It was a lot of work to get the car ready for the tour, including a lot of deferred maintenance (repacking front wheel bearings, ignition system tuneup, plug wires, etc) and having to rebuild the rear end at the 11th hour (including a brand new 3.89 gear and axle bearings). The extra work paid off as I really had nothing to do to the car on the tour but check the oil and tire pressure each morning and keep it full of gas.
Luckily, one thing that I did have the presence of mind to do (after we got to Missouri) was look up the previous owners son (Frank Likert had moved the family to AR in 1983, a year after I bought the car- his son Frankie was 2 at the time). They live in Searcy AR now. Frankie tricked his dad into going to Russellville with him, where we had a planned lunch stop on Thursday). Frank was surprised to see all of the Shelbys in the city hall parking lot, even more so when he saw his old car there. They had lunch with us, then I let them take their old Shelby out to drive around town while we were waiting for the others to finish lunch. They got a real kick out of driving it, particularly Frankie, who had always heard stories about the Shelby (he is a diehard hot rodder and autocrosser now, just like his dad). It was a bigger deal to them than I though it would be, so I'm glad I didn't miss the opportunity to get together with them.
