LS LS1 LS2 LS3 LQ4 LQ9 Timing Cover Alignment Tool w/Seal Installed 6.0 5.3

New timing cover line up tool. GM does have a tool that does this, but it is very expensive. This plastic tool simulates the hub sliding on the crank to center the timing cover. A straight edge is used to make sure it's aligned with the bottom of the block.
