You already have a column that fits, is wired correctly for your year, and is the correct length (remember- in addition to the column shift automatic, column shift manual, and floor shift; there are also power steering/manual steering length variations of each-not to mention the ignition key being either in the column or dash...).
Take a look through the How To/Articles section of the forum- there's a couple of good threads on converting a column shift steering column into a floor shift version. And if you don't want to cut up your collar, there are vendors that sell a reproduction floor shift collar to aid in your conversion.
