Need center to center measurement for Tool 2079

[syljay]

I'm fabricating tool 2079 and 2084.

Tool 2084 is done, it just needs welding.
I'm making my own version of Tool 2079 - which will be 35" long. Then 
I can use my Craftsman torque wrench with a 129 ft-lb setting to give 
me 258 ft-lbs at the crank bolt.

The archive info says that applied torque for the crankbolt is:
With tool 2079 = 258 ft-lbs
Without tool 2079 = 332 ft-lbs

My calculation indicates the distance for tool 2079 should be 15.5 
inches. A reference in the archives says 11 3/4 inches.

To verify, I need the center to center measurement for tool 2079. That 
is, center of socket to center of drive hole at the other end.

If you have the tool, I would appreciate you taking a measurement and 
providing the information.

Thanks,
