Atlas truck bolsters.

Atlas lists 2 truck bolsters, #11880802 and 11880801, that should work, as in stock for $4.50 each.  I have used these on H21 hopper cars.  The other option is to cannibalize the parts from other cars. 

Body bolsters or truck bolsters?

I see where these should work though they are missing some of the frame detail from the H21a bolster. Since posting I have found someone who says he can have original duplicates made. Friday or Saturday I am going to give him a good one to have copied. Can't wait to see how it turns out.

The bolster mounts to the body and the truck mounts to it.

I found someone to print some H21A bolsters. I am going to start out with a run of 24. I am being told most of the cost will be in the creation of the cad program to run them. Hopefully they are not cost prohibited. I need 6 for myself and a friend of mine needs at least a dozen.

The actual printing costs and materials are peanuts, the vast majority of the cost is indeed creating the 3D model.  I though someone had already done the Atlas bolsters?

I had a car with a broken pin. I fixed it by drilling out the stub of the pin with a 3/16" bit, inserting/gluing a piece of 3/16" wood dowel, and drilling out the truck slightly. I drove the truck screw into the dowel and it was fine.

On Shapeways, someone had 3D printed replacement Atlas bolsters.

A picture of the part required would help too.
