     Will we need to do that Bill if we move it forward slightly, forget the
     two outer bolts and use the side clips? I could check at the hangar tomorrow
     but I don't have an oil pan here.

Bill and Paul,
Would it be advisable to use a chemical seal like silicone or one
of the form-a-gasket mixes for the oil pan above the Schertz Beam?
I would think it wouldn't be good to have the beam work a gasket
between the pan and block. Direct contact would be best. It might
even be a good idea to put hollow dowels at several positions to limit
the amount of bolts in single shear. My guess.

The shear on the bolts is minimal given the number that are picked up. The
high loads are compressive directly on the beam when you pull a lot of G's
or during a hard landing.

If you move it forward and only connect the the front pan bolts, and us a clip to pick up side loads, then you can use the original oil pan, HOWEVER you will have to grind off the little lip on the formed pan.
