Re: 3 speed to Muncie 4 speed conversion
Now, with all the above said, to be really trick and fool people, you COULD retain the 3sp column shifter. I would require a little bit of linkage fabrication. I did this MANY years ago on two cars, a 54 Chevy and a 55 Chevy. The reverse position on the column becomes the 1st gear position on the 4sp, 1st gear position becomes the 2nd gear position on the 4sp, then 2nd gear position for 3rd and 3rd gear position for 4th.
For shifting the 4sp into reverse, we used an Overdrive handle/cable from a 3spOD transmission (back in those days a 3spOD handle/cable was fairly common in salvage yards).
Other wise, your option is cutting a hole in the floor for a floor shifter. Hurst has an excellent shifter made specifically for the 68 Chevelle. From the factory, with a bench seat, Chevelles had a boot/bezel and hump for the shifter handle. These 3 parts are readily reproduction from the Chevelle vendors. Here is what it looks like. This is my son's 68 4dr that we converted from a Powerglide to a Muncie (of course, we had to locate and install clutch linkage).
Also, I would suggest placing a Wanted ad and checking the
For Sale adds here to see if anyone may have these parts for sale.
