I have a Casco in my Pontiac, MI built 65 GTO, that unfortunately now has an aftermarket replacement element in it.
Shaker 455 unfortunately lost the original I had when he got overzealous with his wideband meter plugging it in.
I think he was still frazzled from trying to learn to shift the vertical gate
The Rochester lighter assembly in my Kansas City 65 GTO has it's original 1965 element, but it will not fit my MI car- the Casco is smaller in element diameter (or vice versa).
I'm interested in purchasing either one if you have assemblies with the element included.
