Here's a photo of the shifter in my wife's 51 Chevy.Although it's a A883 OD tranny now, the shift lever is in the exact place as the Saginaw lever.The location left to right is between the gas pedal and starter pedal and 9-1/2 inches foward of the seat base.Take a piece of broom stick and place it there to get an idea of the feel, you're a big guy right? You may have to bend the stick over to the right some for leg clearance. It's fine for me, 6 foot 165 lbs.
Hurst shifters never really wear out,a 20 buck swap meet Competition plus model generally only needs a clean up to feel as good as new. But if you don't have a welder and so forth, a new one from Patrick's with the proper mounting bracket and shift levers might be a better bet.
