Paul,  looking at  the Rhino drawing "shertz-beam-clips. jpg,"  I am
struck by its  simplicity and light weight ruggedness.  This version of
the Shertz beam would be VERY INEXPENSIVE to build.

Is the material .063 4130?
How wide are the bent up flanges?
What is the width of the beam?
What is the distance between bolt centers?     From another drawing I
get 27.62"
Are the aluminum end plates  fastened in or just held by the Barry
Mount bolt?  How thick are they?
Does the pan need modification?
       Thanks,  Jerry

27.62 inches or less  is optional with a beam type side mount.
Bill used that dimension to allow exhaust system clearance with a simple tripod mount.

Yes on the 4130 tubing or hat section sheet. The flanges are one inch wide on each
side. If you made the hat section deeper, say 1.5 inch or 2 inch instead of one inch
you could make the flanges only .75 wide. The blocks are 1/2 inch thick aluminum
bar stock. They should be riveted to the steel with long rivets at all 
four corners. This prevents them from working sideways and wearing out
the rubber motor mounts. Up and down is no problem. Fore and aft is no
problems as they are nested in the hat section.

Should be no oil pan modifications.
