This is probably "old hat" for most of you, but being new to the LS scene, I've found that there are a couple of special tools required for an engine build, one of which, is a damper installation tool. Instead of just purchasing a bolt and nut from an ebay source or drop the big bucks for a real tool, I decided to make my own from hardware store items (washers, steel pipe, lawn mower bearing for a centering device, and a metric jam nut) and two specialty items (11" stainless rod and nuts, and a thrust bearing). Here's a pic of the parts. Some assembly is required;
Now I can button up the 5.3 for my '80 C10
Later...
