I know that nearly everyone who's on this board is a "Purist" and doesn't care much for modifications but, has anyone swapped out their original Muncie 4 speed and installed a new 5 speed in their car? I have a 68 SS with bucket seats and a 4 speed with the console. I'm going to put a Tremec in this year, hopefully, only if I'm sure it will work with the original console.From what I've read and seen on line at Silver Sport transmission's website,looks like it will. May have to cut the tranny tunnel a bit,any thoughts?
