If you want to stay with a column shifter you may want to check out the cpp's ebay store. You could kill two birds with one stone and replace the whole steering column. It's probably more than you want to spend but if you think you'll be in the market for a steering column in the future, it might be worth it.
I got one similar to this one: (but mine was all stainless and was $300):

You'll also need a u-joint as well (around $50 on ebay if you search)
A sloppy shifter was the whole reason I got mine since I don't like the idea of a floor shifter.
