There should be a FEDCO badge on the dash of your car, look closely at it and you'll see letters and numbers stamped in it. Do not try to remove this badge or it will be destroyed. Send the numbers to the Chrysler Historical Collection people at the museum in Auburn Hills, Mich. and they will sell you a copy of the original build sheet for this car. Found an old card for them. Corporate Historical Collection, CIMS 488-00-00, One Chrysler Drive, Auburn Hills, MI 48326-2778 Phone (248)944-0437
Good luck!
