It's been A while since I've been on but I have been toying with the idea of throwing a line lock on my 07 GT500. I was going to install a SLP line lock a while back but never pulled the trigger and now I see they aren't available. A few other places like JPC list them for the 10-14 models but not 07-09. The only kit I have seen available is a Hurst one intended for GT models but says it will work with GT500. Anyone have any good input for me?
