I am putting a C4 behind the 289 that replaced the 200 in the Ranchero. I was told by someone at Dearborn Classics that I would need a column shift control selector insert and that they were no longer being reproduced. Does anyone know where I can get a hold of one of these? Or is this a part that can be machined? Or what my other options, if any, would be?
As always, any and all help is appreciated.
