Later model bucket seats in early A's

im sure you can get a auto shifter to wok with ur bench seat, we just did in a 1974 scamp new hurst shifter,,with lever to unlock handle,,plenty of room,,some shifters are to long to use with a bench seat,,

but to answer your question,, i use a set of 1972 cuda buckest seats in my 66 baracuda,, i used the 66 seat brackets,,fit nice if i rememebr did it a looong time ago,,,but think im going to go back to the correct period seats,,,
