At the end of the day, it drove home all 850 miles under it's own power. Actually, it drove all but about 150 miles of the trip.
The roll pin that holds the distributor gear broke at 3500 rpms on Highway 90, about 75 miles east of Missoula. We diagnosed it and fixed it after the show on Saturday. A one-armed Canadian FE guy gave us the suggestion of what may have happened and he was correct--God bless him! A helpful guy from the Bozeman Ford dealer's body shop talked the boss lady into opening the body shop and he just happened to have the roll pin in his toolbox and he drove the broken pin out and popped the new one in for us. We fixed it up on the trailer in the motel parking lot (I'm sure they were thrilled to have 1/2 my car scattered over their lawn alongside the building) with my mini tool box and only one trip to the autoparts store in the Boss. First try on the distributor was 180 degrees off, of course, but another complete turn of the engine and that little bad boy fired right up and drove off that trailer immediately.
What doesn't kill you makes you stronger, and each of these trips is a new learning experience for me.
