Jeff,
A friend of mine who also frequents this site (amuseme) knows of a '68 300 deluxe car in our area. I've seen the car but it's been a few years. One of the last conversations I had with Jeff (amuseme) was centered around this car and the fact that he might buy it. I'll check with him or ask him to reply to your posting here. Maybe we can come up with something.
Aside from that, try asking Don Lightfoot. Maybe he'll sell you the panels from his old and worn out '69 Deluxe!
(Sorry Don; you know I'm just kidding!)
BTW, I too enjoyed meeting you and Nick at the reunion last year. Again, same table!
Dennis
