These pictures were posted recently on the Photo Site with a question, what is the part?

This appears to be the Passenger side baffle used on the 77 & 78 coaches with he 403 engine. Appears whoever removed it cut the rubber side walls to get it out. There is a picture somewhere that shows how they were installed. These were added to direct the air thru the radiator and not let it go around. Ken H has a good album on how to add this type adder to your pre 403 and if they have been removed from your present 77 403.

Thanks to Bob Burkitt, he supplied me with the Drawings of the baffle assembly. I know that I had seen them earlier.

Anyway here they are for anyone interested.
