So could you please invent us a bearing assy for the idler arm then? I really like the idea esp with a welded k frame.

In a k frame related issue from running lots of laps - Even with one of the good urethane mounts the engine needs to be restrained a bit further. I have found the need for a second Schumacher style torque strap installed on passenger side of the k frame. What is happening is the engine is compressing the right side mount pushing the collector[tti] and exhaust system [tti]towards the ground. Holding just one side makes the problem worse. It can be seen in the pics of the cars at speed and in the tearing of the rubber portion of the exhaust hanger at the muffler... I had this problem is with both bb/sb engines. The 2nd torque strap is a pita but it works.
