Engine Centerline - Dimension

When I installed new TTI headers on my 68 Cuda I also put solid Moroso mounts on it and it was real close to what TTI said. I had to put one thin shim (About .075") under the drivers side mount to raise it so it cleared the PS box good. Before I ordered the TTI's I had a NIB set of Doug's I bought from a member here. The drivers side was made wrong and no way would it clear the torsion bar even after I beat the snot out of 2 tubes. Gave up on them, sold them at a big loss and ordered a set of TTI's. Went on easy peasy
