What knob did you use. BTW a very good looking Viper
I just installed the Mopar Hurst Shifter with the hurst knob. I left the nut above the boot ,then I aligned the viper logo on the shift knob in correct position, also with the knob screwed all the way down it was to low for me so I adjusted the nut so the knob would be further up on the shaft.
Shifting was still hard for me so I used the first strike mgw shift knob. A little higher but this gave me better leverage and was, for me, much easier to shift. I had to do this because of my shoulder problem.
Thought you might like to see pic of install with Hurst Knob-could you put on a pic of your install
