Hi Robert,  I do in fact continue to make Rotary engine mounts using the S beam design.  The S-beam requires a custom oil pan which I can supply as well.  Here is a pic of the S-beam  for a RV7A with the pan flange bolted on.  Next step is place this in the fixture and build the engine mount.  Then the pan is completed.   This beam is asymmetrical to provide room for a rad on the cool side. The bolt holes that go through the S-beam are bushed.    You can contact me at jerryhey@earthlink.net.  Regards,  Jerry
