I can't believe you don't already have an aftermarket shifter on that car.. You should do that mod before you even consider anything else. I have a tri-ax on my car and the difference from stock is night and day. Having said that, I'm sure there are plenty of people here who would make the same case for pro 5.0/mgw/hurst/etc(non-stock) shifters.
Yea I can't believe it either lol.
