Does anyone know which is the correct bumper jack base for a 1965 Acadian? I guess there are 2 shapes of holes.

End view. So just the t not the triangle one?

Do you need the base?  I might have one.

Thinking "T" bar style is right. Notch style and tooth style. My lingo but "T" is tooth and triangular is notch.

Can see the teeth in T bar

Notch style

I do need one if you have it. Let me know as I do have Menno checking too.

thanks all!
