That's one part where paying a bit more can make the difference between life and death. I remember back in 2001 when we bought our bird, replacing this part was one of my very first projects. Replaced it with a cheap one from local parts place. One day while at a local car show in Lancaster, PA a guy at the car show says "have you looked at your rag joint lately".
I looked down at it and almost crapped myself. Dam thing was torn through one side. I mean completely through. How it is that I couldn't tell is beyond me. That joint had only been in the car for a few months at that point and had slid apart, torn one side and was down to just one rubber side holding everything together.
I actually had the car towed home I was so scared to drive it! Ordered the "good one" from Ames and it was still on the car when we parted it out ten years later and looked perfect!
Sometimes it just isn't worth trying to save money on a part IMO...
