This little beauty evidently was used on center head bolt on 34-46 Chevy cars and trucks. I'm sure many enterprizing mechanics found a way to torque this bolt without this wrench but its interesting that it evidently was so challenging that a special wrench was designed for this one fastener. Marked KMD189-10 and 41-W-2965. If you need this wrench for your Chevy I would loan it with proper surety.

At first I thought it was one Strik9 had modified!

Nice wrench!!!! That thing is cool!!!!
