Will GM 200r4 work with factory floor shift location?

I mocked up the possible set-up required to use the stock console shifter in mopar a-body with a 200R4. After lots of measuring under the Cuda I'm 99.9 percent sure it will work, the only possible problem relates to Murphy's Law. The vertical shaft (the one clamped to the 1 X 2 box iron) represents the torque shaft in position. The thin sheet metal attached to the rod represents the arm that moves back and forth. The small horizontal rod ( actually a piece of square stock) is the rod that goes to the shifter bracket/arm. I had numerous Chevy shifter arms and picked the one that dog-legs toward the outside. It's best to keep the shifter arm and the arm that comes off the torque shaft on the same plane (vertically and horizontally). This way the load is in a straight line making it easier to shift and putting less load on the pivot points. The arm that comes off the torque shaft is exactly 3 1/2" center to center. With an arm that length the rod that attaches to the shifter moves 1 1/2 inches from "Park" to "low" gear (Cuda). So I selected a spot on the shifter arm that moves 1 1/2" as the shifter arm goes from "Park" to "low" gear. If you look real close you might be able to see the small silver/gray spot on the shifter arm, that's the spot where I would drill a hole for the lower shifter rod to attach. If I keep the torque shaft arm the same length (center to center measuring horizontally) then the stroke will stay the same (1 1/2"). Of course you can make it any length you like but it will change the stroke. Just remember that the longer you make it the more unstable it gets giving you a sloppy feel at the shifter handle.
I've done this type of stuff before but with a 700R4 and with a three speed shifter (like the Cuda) you have to give up a gear. There are only 6 detents on the Cuda shifter but the 200R4 has 7 detents. On my last build I gave up low gear rather than trying to find a detent plate with sufficient detents that would fit the console. Parts houses sell shifters with all the detents you need but the console won't look stock any more.
I'm sure it's going to take some more tweeking but if it was easy EVERYONE would be doing it. FYI, the Cuda torque shaft is 1/2 rod so I'm thinking about buying a helm joint and use it as the pivot point just above the arm. On the Cuda the arm is above the pivot point (see previous pics). But there's no way to put the pivot point below the arm because on the Cuda the large bracket that supports the pivot point is attached to the underside of the tranny (see previous pics) allowing the torque shaft to extent below the tranny. The 200R4 is to wide at the bottom so the shortened torque shaft will have to have the pivot point above the arm. Putting the pivot point above the arm shouldn't be a problem as long as you don't extend the torque shaft to far beyond the pivot point. If you extend it too far it will flex and give you that sloppy feel at the shifter handle. I plan to extend the torque shaft about a 1/2 inch below the helm joint, you only need enough below the pivot point to weld/attach the arm. At least that's what I'm going to do unless someone has a better idea??
