Alfonso, there is a roll pin in the coupler that has to be removed first. However, what I recommend above all else FIRST, is to buy a factory service manual for your car. They are relatively simple beasts, but there is no substitute for the correct repair procedures straight from the factory service manual. I just recently acquired one for my 63 Dart. It is well used and the cover is worse for wear, but the inside material is in perfect condition. I paid 20 bucks for it. You can also get them on CD, but I am old school. I would rather have print.
