Greetings all,

I have a 58 retractable and am in need of the knobs for the vent door. I am finding nothing on the web for 58 and 59. Lots of 55's 56's and tons of truck vent door knobs from the late 50's.

Does anyone know if they're interchangeable from the late 50's. Kind of curious why 58 and 59 Fairlane vent door handles are so rare???

Tom
