Almost every line from the wrong stuff leaked, and they sent the wrong prop valve for my car, which I had to pay for to replace everything from someone else that didn't leak, but the biggest thing that got me was that lack of knowledge they have. The rubber hoses that go from the drum, and or caliper to the hard line at the frame rail didn't have any of the splines that hold it from turning in the tab welded on the rail, and I couldn't make them understand what that was, and they sent me another set just like the first, so I have two sets of hoses that can't be used. I think I sent a picture showing it. Also, all of my fuel, and return lines from the front of the car to the back were hand delivered to them, cause they didn't have anything for a 71, and they couldn't reproduce them so that they would fit the car without modification. Shame cause customer was really good, they just can't make anything that works.
