Lon, thank you for all the positive comments. I have no doubt that the staff at the asylum will treat me with kindness and the deepest sympathy.

| Great work John! I remember visiting your shop when I was working in cal for a few days and holding a prototype in my hand a couple years ago. Thanks for the persistance and never giving up. It must have been frustrating at times, at least you will be able to meet the people who have been behind you at the assylum. Keep up the great work. May I ask how many sets were run on this first run, and how many have already been accounted for?
 55 Vicky & customline 58 Rack Dump, 55 F350 yard truck, 57 F100 59 & 61 P 400's, 58 F100 custom cab, 69 F100, 79 F150, 82 F600 ramp truck, 90 mustang conv 7 up, 94 Mustang, Should I continue?
