Here is a thread on LS1tech with a bunch of fitment info on the Tru turn and the new holley engine and trans mounts. Hopefully it will give others an idea of what oil pans, motor mounts and headers can and cant be used with the tru turn setup.

Question for Ridetech. What pitman and idler arms were used when you measured the bump steer? Stock my car came with two different length arms as did most 69's from what I can tell.
