Cool, lookin good! If your driveshaft isnt about to fall out you will probably be fine. I had my buddy make me a square drive shaft when I did my 63s/wranglers because it only had about an inch and a half of spline before it would fall out (on flat ground). I am doing dual cases eventualy so I did not want to spend big $$ on a custom driveline only to have to have a new one made later on. You can probably find a local shop to make one out of your stock front driveline for realitivly cheap. If you arent going to do any major upgrades though you may consider spending the money on a more permanent driveline than just a square.
