I want to purchase thw 20" rims trhe 4.8's come with for my 4.4. I see that there are company's who make reproduction rims for alot less money. Any idea on the quality of these aftermarket replicas or where I could buy OEM ones. Thanks in advance.

Are you still in Germany? If so, there should be lots of options, but one of the larger wheel retailers is D&W http://www.dundw.com/ (http://www.dundw.com) I expect they should have something available from the aftermarket...
