Hi Wayne. That shifter is quite unique and I would be surprised if it could be made to work. The arm seems very long and getting the corresponding arm on the trans to match the detents on the shifter might be tricky. Not saying it can't be done though. I recently used a Shiftworks shifter in a 4L60E install and it worked very well. You could likely make it work in your console with a bit of fab. Shiftworks has a good selection of cable lengths and has several arm options for the 4L80E.

Another option might be a shifter out of a 4th gen F body. I used one in my Firebird. The cable length was tight but it worked well.
