....also keep in mind, mine is a 64. Yours is a 66. I know the 4 speed humps are different for those years, so the transmission tunnel could be different and wide enough. You're just gonna have to "see".
Yeah I know 4 speed humps are hard to come by and different for 66. Would be interesting if the tunnel floor was slightly different. I wouldn’t count on it but never know with some of these Mopar’s haha.
