I'm looking for both left and right side defroster ducts for a Henry J. I'd like to have the second generation "fresh air heater" defroster ducts if possible, but then beggars can't be choosers. Look in the Henry j / Allstate forum under, Defroster ducts? and open the 100173pdf to see a complete parts list and illustration. Their factory part numbers are left-212674, right- 212675. Thanks for any and all help and many thanks for those who make this forum such a great resource for information. Don
