Fishy68,
From your post I'm not sure if you want to go back to the stock shifter or if you want to make the aftermarket shifter work in your car. Either way here's one way to get the aftermarket to work.
I've used cable shifters on other cars with 200R4 and 700R4. It should work on any car. The trick is to put a lever on the trans shift shaft that has a hole in it that is at a distance that will match the throw of the shifter handle. If you read all of my post I kinda talked about it. I chose a lever to put on the trans (see pics) that allowed you to have a throw of 1 1/2" because that's what my Cuda linkage has. But in your case it will depend on how you hook-up your cable. On the shifter handle you'll have to figure out where to attach the cable so that you get the correct amount of throw so that your transmission goes through all the gears as your shifter goes through all the gears (basically you have to match the detents of the trans shifter shaft to the shifter handle detents). Sometimes, like I've done before, you can hook up the cable directly to the levers under the shifter handle, sometimes the shifters have various holes so you can pick the amount of throw.
But in the end the easiest way is to hook the cable directly to the shifter and install a lever on the trans that allows you to match the throw of the shifter in the console. Just imagine a lever 3 inches long on the trans with a hole every 1/4" or every 3/8". Now you simply move your shifter cable from one hole to the next until you match the throw of the console shifter to the throw of the trans and it's done. To tell you the truth I've done it exactly like that and as luck will have it the spot you need turns out to be between two holes and you then have too make another lever. Of course you can make a slot in which case problem solved.
Hope this helps...where are the pics of your ride??
