I took the Jeep to Cruise Night where hundreds of (mostly) old car and truck enthusiasts gather to see and be seen. My friend Paul introduced me to Bob who finds/buys/sells old Jeeps and Jeep parts. Bob and his wife were on their way home (Colorado) from a Jeep gathering in Ohio where Bob purchased an old engine block.
As fate would have it, just the engine block I’d need if the tiny crack in my block (see image below) made the Jeep un-drivable.

So I bought it for $100 and will keep it in the Annex as Cosmic Insurance against my current engine blowing up.
