[oletrucks] Deluxe vs. Standard Heater, 56 half ton

["Kinderlehrer" <Kinderlehrer@comcast.net>]

The parts suppliers all list 2 different heater blower motors for the '55 
through '59, one for the standard heater and one for the deluxe heater. 
What's the difference between them and how do I know which to order?

Thanks for any help, Bob
