I checked my 66 and 67 TSMs. The 66 four speed shifter is ONE YEAR ONLY. It is basically the same as the 63-65 Twin-Stick shifter, with the obvious modification of three shift levers instead of only two, and no OD lever. You can't modify a T-S shifter to shift five gears (4+R) without the extra parts. The 67 and later four speed shifter bolts to the transmission. The 290 and four speed were mid year intros on the American. I would assume it used the 67 style shifter, though the 66 style would fit and work. I don't have a 66 American TSM, just big cars. Since it was a mid year intro the four speed and shifter won't be in the TSM though. Oh yeah, I forgot to add MARLIN to the list of cars that used the floor mount four speed shifter for 66. Any Marlin, Classic, or Ambassador with four speed will use the same shifter. All four speed cars used a console, the same console as used with auto floor shift cars. The auto shifter mounts on the floor in a metal "hump" just like the four speed shifter. This will be a hard to find item! I've occasionally seen a Twin-Stick shifter, but only a very few four speeds. The console with no shifter has the shifter hole under the overlay IIRC. You just need to change the overlay or cut the opening in the no shifter overlay. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AIM.html (free download available!) -------------- Original message ---------------------- From: "Swygert, Francis G MSgt 436 CES/CECM" <Francis.Swygert3@xxxxxxxxxxxx> > Good luck Dan, you're going to need it!
