I'm thinking about picking up an aftermarket automatic shifter and would like to know if anyone knows of any that will fit under/in a factory A-body console? I have been looking at various shifters and kind of like the looks of either the Hurst Pro Matic or B&M Quicksilver shifters in particular. Has anyone used either of these shifers with a factory console? If so, did you have to modify the console at all and if you did, how so?
