which shifter handle ?

The 833 is a bear to shift compared to other trans,..

I personally found that I missed more shifts with the shorty handle,,

I feel the longer handle gives me more leverage, I put my whole body into the shift,, and found it uncomfortable/impossible with the shorty, especially 2 - 3..
I did quite a bit of fumbling around trying to grab the T-handle ! .... Factory stick is back in the car !

The short handle is mainly used when the shifter is mounted higher to be able to use the straight linkage rods. I have had a couple of those setups in the past and they are a lot of fun to drive.

To see what that looks like you can search the mechanical parts for sale section here, early in the year there was an aluminum case 18 spline 4sp for sale offered by a guy named Dorian in Canada. I found the ad by searching under either hurst super shifter or super shifter III.
From what I understand, you can use the straight rods with the shifter bolted in the stock location ? I know for sure that the Hurst Ram-Rod inline shifters mount higher up and further back than stock shifter boxes. At least that's how the B-body ones mount, which pretty much puts them close to the A-body mounting location.
