Well made kit, must have for LS engine work
Well made kit. Must have for assembling your LS engine. Each alignment jig also doubles as a seal driver which is very helpful. Instructions are easy to follow, just wish the print was bigger because I'm old and blind :)

Well made!
Used it to install the rear seal and worked very well. Don't pop out the plastic insert. It's used to align the seal. Put it (the seal) over the end of the crank and put your fingers at 10, 2, 4 and 8 o'clock and push the seal in. Use the tool to tap the seal in until it bottoms out. (service manual indicates the seal should be tapped in until it bottoms out).
