Hurst Pro Matic shifter

i have a Pro Matic shifter in my 66 dart with a 904 trans. I am having a lot of issues getting it adjusted. My valve body is a standard forward shift.
The first issue I had was the original cable melted down due to the header heat. I replaced it and this time I have wrapped the cable in 2 different types of heat wrap which is doing a good job of protecting the cable.
With both cables I put the trans in neutral and adjusted the cable from that position with shifter in neutral as well.
I have all gears from park to 1st but what I find is that sometimes the shifter will need to be bumped forward twice to get it to go into drive. Once in a while i acts like it does want to click into drive and I have to bump it a couple of times. Ive tried moving the cable forward and backwards in the bracket for adjustment.
Are these shifters just not a good quality. should I think about a different shifter? I like this one because I was able to mount it into the console where it looks like it was factory. What would you recommend to try to help make this operate better. Or is it just a matter of using it until it loosens up some from being new?
Here are some pics of it in the car. It has full range to move inside the shifter area without hitting anywhere.
Thanks Rod
