1920 Model O Four Passenger Coupe

Unknown

Greetings all,



As some of you know I have a 1920 Model O four passenger coupe. I need to

redo my exhaust system and two issues have come up:



1. The exhaust packing nut on the end of the manifold is broken...I need to

replace it...does anyone have a spare to sell or has someone reproduced

these?



2. I would like to get a diagram as how the exhaust heater box is plumbed. I

know where it comes off of the main exhaust pipe right before the

muffler....but I am not sure how it is plumbed out of the unit to the rear of

the car. I do know from a period factory photo that it ends up on the

opposite side of the car from the regular exhaust pipe.



Any help would be greatly appreciated........
