Aftermarket shifter in a stock console?

The mechanism is worn. It's impossible to choose the first gear, now I am able only to use Park, Rear and Drive. And the indicator and chosen gear donĀ“t match.
B&M makes some Good Cable driven replacements but I would try to see what's actually malfunctioning. It could be a simple fix. Does it all work just fine when manually shifting directly at the Trans?? I haven't personally installed this but it looks pretty Sweet. http://www.summitracing.com/parts/BMM-80701/ Any way here's a bump for you so someone who's done it can chime in.
