"Old Guns?" Or the "Unforgiven"?

In 1968 I was 17 and was living in a little town in eastern Washington named Pateros.
My best friend was 19 and owned a 67 GTX. He had taken the X to Spokane and had the 440 built up a whole bunch, this thing was wicked fast and ruled the roads around those parts.
We put some tires on it one time off of a hudson panel truck, the rims where 16" and the tires where real narrow. You should have seen some of the burnout we did with those on. Donnie would wind it up and a couple of us would push the back end back and forth across the road, made some pretty crazy looking marks on the road.
