Peter. I think Hartge or Alpina used to make a windage tray. What I did on my E-30 was weld a small lip on the inside of the right side of the pan, then build an aluminum extension on the right side of the pan, it looked like the bump on the left side, that and an Accusump and I still had pressure drop on any left hander. But I ran it that way for six years checked the rod bearing once, they looked good so I put them back.
Good luck.
