I've had a set of PDR towing twins laying around for over a year now without the time to install. Well yesterday I had the front end tore down getting new ball joints and found out Napa sent me 3 uppers and one lower (Yeah I shoulda checked all four boxes before I took the truck apart) , But anyway with the truck disabled all day I finally had time to do the twins. We got stock stuff cleared out and have started in with the new. Should finish pretty easy tomorrow. The only problem I have had so far is that a picture is worth a thousand words. And my instructions had to be faxed to me (lost the goods some time over the last year) and the pictures are worthless. The part I wanted to see was how the turbos were clocked. I don't understand why PDR didn't have the turbos clocked correctly when they sent them but they didn't and couldn't really explain why. For that much money it looks like they could have done that small step. But other than that every thing else looks great. If tomorrow goes with out glitch I'll tell you how they do.
