Inland Shifter

Do you think the longer shifter would work? Do you know how much longer it is than the A body one?

If I were to hazard a guess, I'd say no it won't work. I do know that all the linkage won't work, and the shifter handle was longer, as well as bent at an angle back to the driver, that the A-body shifter doesn't have. Trade it to a B-body guy for what you need.
