I personally have been ticked off by treadstone a couple times. First about thier intercooler not actually fitting behind my Talon bumper and second because they sond me a OIl Supply line kit that was WAY TO FUCKIN SHORT. I had to go right over my valve cover because there simply wasnt enough slack to route the line around the right side ( battery side) of the valve cover. you can see plainly how I had to install the lines!! I called Treadstone and the ass is line " um well go buy a longer line then at the harware store" and then I ran into the issue that the 420a has a 3/8" NPT hole on the back where the oil sender plugs into. This Treadstone guy sent me a 1/8" NPT. I called him on that one too. His response was to go buy another fitting from the store that fits. What kind of service is that??!?

Heres my original post when it happened.
