All is good - this thing rips. When I jump in my 5th gen it's just not the same.

I can't say if the alternator pulley is different sizes from early V8s to later V8s...but I do know for a fact that the serpentine belt tensioner pulley did change size from 2003 and early 2004 V8s to later 2004 and onward V8s, the 2003 and early 2004 are 102mm and the later 2004 and onward has a 90mm pulley.
I discovered this fact when I had to replace my tensioner pulley, I just happened to get a rough measurement of the pulley before going to buy one and it measured approximately 4" and the pulley he tried to sell me was approximately 3 1/2" and I told him it was the wrong pulley that mine was 4" he tried to assure me it was the correct one listed for a 2004 V8, so I had him look at a 2003 V8 pulley and it was 4" which is what I needed, I also had a very hard time removing the old belt because it appears that when the PO had it replaced they used the belt for a 3 1/2" and when I installed the belt for 2003 it was easy to install, I would have never been able to get a belt for a 3 1/2" pulley on, at least not as easily as it should be, I'm not sure how whoever replaced the belt got the old one on but I almost sure it was partly responsible for the old pulley failing when it did besides age and normal wear and tear.
