Gennie. Fairly intuitive for a driver new to the car. Mine's over ten years old. I advise you to set the friction adustment a little tight before the first use. Mine was about right, about 1000 miles down the road a little looser but it's stayed in adjustment ok. Gennie E-Brake as well - the 32's is 15 years old and no probs except on the install where one tooth wasn't quite deep enough. A few strokes of a file fixed that. Got a Gennie E-Brake in my 31 as well. Using a B&M competion shifter in that cuz I had it. Extending the reverse cocking lever will make it very nice for street use.
I've used both and I recommend Gennie. I found it way easier to adjust the neutral safety switch on the Gennie and I've never had any trouble with it. The Gennie shift linkage feels more positive to me. The Lokar has been known to jump out of gear on rare occasions on very bumpy roads. Also Gennie's customer service dept. was more helpful to me than Lokar's was. That's my $.02.
I got a Lokar it rattles and does bump out of gear once in a while but I think tightening it up would do the trick. Most of the problem I think is the height of the shifter mine is the 23 inch so it will get to moving do to the length of the shift arm. I will go with a B&M next time.
Gennie looks more traditional...I dont like the button on top...To me that looks too modern...every pastel street rod with IFS has one.
I have a Lokar with the adapter to use a standard shift knob and it works great. Have never ued a Gennie though for comparison.
