That will probably be adding more cost than anything.Is there a downside to the adapter U-joints? Sounds cheaper, but I don't know anything about it. I'm not exactly sure. The stock drive shaft has 310's on it ... the bigger aluminum driveshaft has 330's on it. I'd guess that a full 330 u-joint is stronger than a 310/330 adapter style u-joint ... but I'm not putting any type of crazy power to it, so I wouldn't foresee it being an issue. I'm sure the stock non-adapter style are probably more readily available, but when you can order just about anything "special" online does it really matter that much?
