You know if you have a welder you can make a square front drive shaft on the cheap for the cost of steel and the price of a solid axle stock front shaft. Or have a shop make it. my friend made one out of my stock 85 for me at his shop for $60. Its cheaper than 200 bucks and stronger since there are no splines. ive been running a square front for over a year and if done right they wont make hardly any noise.

This is the only pic i have of mine but you get the idea
