Has anyone ever threaded an f-body shifter to the std Vette threads?

I have a MGW **** that I used in my Z06, I'm real comfortable with it and would like to used it on the new F-body project. But #1 MGW isn't making these anymore and I asked if I could have them custom make one... I got this reply... "i am sorry but the **** body we use is too small for a 16mm thread . we have tried it in the past and it did not work."

So has anyone done this?
