What kind of beam are you likely to use? Wood or steel? Standard I-beam?
Square tube?

Gary,,, I was thinking 4" I or H beam if I can find one cheap. Something on each end to fit in the slots of the pin boxes. Then a chunk of steel in the middle. Only have about 6" of clearance though,,,,,,PL

Paul, still consider two 4" channels back to back. You could use plates in
the ends that are cut to reach around the bogie frame and hook into the
opening (ala jack hooks), and bolt or weld those plates between the
channels. That would leave a gap. The center foot could be another plate in
that gap, with a foot welded to the edge of the plate sticking down below
the beam, and the foot being pivoted onto the channels with a hole through
their webs. I'm thinking that will be easier than trying to affix fitments
onto the ends of an i-beam, and 4" channel is a lot easier to find lying
around than S4.

i'm not sure what you will gain over the method of jacking the front up in the center and adjusting the leveling valves at the rear to get it in balance then adjust the front pork chops.
