Hemi 4 Speed?

Why wimp out at somebody's suggestion it won't work, or that you can't do it, or that you won't like it. The 18 spline boxes were the strongest ones of all, and the "slick shifted" ones were the hot setup for up shifting from one gear to another (as in drag racing).

The syncros have been MIA in my Duster for well over 100000 miles. Pulling it into neutral and winging the throttle to downshift is SOP, and has been, for at least the last 10 years of using it to go back and forth to work. Of course, I learned to drive a stick in a "borrowed" stock non syncro 3 speed Model A 45 years ago, and drove "big" truck for well over a decade, mostly rowing a 13 speed Road Ranger, with and without the help of a clutch. I'd use a slick shifted HEMI 833 in a heartbeat.

Just remember, if it is indeed an E body transmission, you'll need to shorten the driveshaft and make a plate (no doubt covered here, check the archives) to mount the shifter in the stock A body location if that's what you're stuffing it in. Might as well spring for a REAL Super Shifter too (also covered here in a current on going thread) while you're at it.
