Sorry. Thought I had pics of shifter close-up but don't. On my 65c10 and previous 67 gmc the shifter sat quite close to the seat and tucked close to my leg. Right hand fell right onto it.
I'm a big guy. 6'4". Seat all the way back. This shifter would be tight if you were short legged and needed to move the seat ahead. Hurst makes a bolt on shifter handle for 567 chevy cars that kicks ahead and then back to clear the bench.
Ultimately an s10 T5 would be the way to go. I saw a 62 chevy truck that had a 5 speed in it. Shifter was about 4-5 inches ahead of the bench and centred on the hump.
