Thank you so much for your trouble in looking up the replacement part number. Turns out though, I don't have the Muncie 4 speed tranny afterall. One of the previous owner's installed a Borg Warner T10 tranny, apparently off a 63 vette. So the switch assy that I bought won't even work. Guess I'll have to use the switch that gets installed on the Hurst shifter. Not happy about that.
My other auto is a Glock! Due to price increases, I no longer provide a warning shot.
