Lokar Shifter Issues

[Mr Blue]

Well,
In between this boat project I decided to take Mr Blue out for a spin the other night. I showed up at the restaurant and went inside. One of my buddies said that someone wanted to hear my engine. So I went out, fired it up and the shifter fell into reverse!!!! (Renamed from Mr Blue to Christine) I quickly lunged for the stick and jammed it back into park, BUT not before it tapped the front bumper of a Mustang behind me!! After the smoke cleared with no damage to my vehicle and a small 2 inch line of my paint on their front bumper (Still cant find where the paint came from, NO damage to my car) I realized that I have had it with the Lokar shifter I installled when I built the car. Pops and I have adjusted and tightened that darn thing until we are blue in the face and yet it has never been right. It is tall (23 inch) and it has the large but light skull shift knob (the factory Lokar knob was heavier) but gosh it should be safer than this. Anyone else had a simular problem with their Lokar/ Considering changing to a Gennie. You thoughts out there?
