I have a 69 cuda that I want to put an A/T console shifter in. I know the 66-68 shifters are a little different than the 69-76 models. From what I can tell its mainly to do with the knobs. So my main question will a 66-76 shifter fit my cuda? Are A-body shifter's their own, or will B-Body shifters work as well and what year? Thanks.

Yes the abody stuff interchanges
The bbody is different
The only bbody part that would work is the shifter itself. But is slightly different
