Keep your stock shifter.

I ran a cheapo ebay shift for about a year. It shortened the throw a little and made the gears feel a little tigher.. but then amazingly my gears started grinding.. the short shifters are very rough on your syncros because they decrease the amount of time they get to mesh before changing ..

Then i was leaving a drug test and the motherfucker broke off at the ball, leaving me with no shifter.. ended up having to get a friend to find a shifter for me, bring me a jack and change shifters in the chic fil a parking lot. sucked ass. wasnt worth the short throw or the $25 i spent on it.

Fuck short shifters.
