rear main or front timing cover you need these
If you are doing a rear main seal or a front timing cover you need these.I did a rear main seal without it and I regretted it because I had to do the job twice.Nothing like seeing oil leak out the rear main seal after you just replaced it. Ughhhhhhh

Item as described in package seems well made
Haven’t used it yet, hopefully it holds up to its job task. Most likely will workout just fine..

Good quality
So far I’ve only used the one for the rear. Fit was perfect on an LS-6. I expect the front jig will fit as well when it’s finally time to address that seal.

Nice
The front positioned is a bit bigger than I expected but they look good. I've seen others that are smaller but they didn't include the front and rear or the pan front lip
