I have that same shifter in my car. best damd shifter by far. its easy to opperate with one hand. slim enough to fit in a pipe rack dragster. and best of all fail proof. I asked them about there warranty and they replied , I dont know if we got one because we have never had one come back broken.
My friend first talked me into them when he told me he has one in his promod for 12 years. He said it never skipped a beat. I was sold then but after having one in my car for 2 year, I'm there best salesman. I'm switching to a powerglide as we speak and they told me they will just ship me new side gates so I dont need to buy another shifter.talk about customer service .
