Uh, why not search for it. Especially since you started it. Should be easy to find.
On a side note, did your buddy dyno before and after the DS swap?

UH, because there was not much reaction and my question was not really answered so, why look for it? But thank you for doin it! The reaction I did get was from one or two people and they claimed that it would not get a lot more power to the ground! I believe you stated that it was just too expensive and other than that, there was not a lot of reaction or answers so, I am trying it again! My friends car was not dynoed before and after as the DS was the first thing he changed and said he noticed a lot. The vette doctors dynoed it after quite a few mods and again, couldn't believe the numbers! They said that with his mods they expected 25-30hp less! His GTO has bolt-ons, which include headers, NO exhaust stock cats, and a cam and it dynoed at 422hp and 398 torque. The car runs well, trust me!
At any rate, I may be the guinea (sp.?) pig as I may get a great deal by a driveshaft shop to try it. I am debating on whether to do it or not with the feedback from you guys. I guess nobody has done it yet and that is surprising, I guess! I do not know what the great deal is yet as I will speak with him tomorrow, it was my friend who asked me if I wanted to do something like this and really didn't want to after the responses I got from the last thread! Then, I looked into more and I am deciding on trying it. I was more or less wondering:
Why we have this 3 piece driveshaft and what are the negatives to going to a one piece?
