2 - The paper gasket between the tranny adapter and QT was deleted and a groove was made for a rubber seal (o-ring) there. I imagine you can use the paper gasket there but I'm not sure of that.
3 - The vent is no longer a cap style. The vent on the Edrive shifter inspection plate has a nipple and uses a 3rd metal tube to vent up at the firewall in an upside down J shape.
That said... After 41 years, the QT could have been swapped out for a 73-78 unit too.
i work on my Chief like a 1978 model. Have the glas fuses, 3 part bumper, razor grill. But my VIN is a 1979...
I use the QT pages of the 1978 TSM and know the jubilejeep pages, but have not compared all pages. 1978 should be fitting or not?
