I would go through Bruce and Bobby's Boss block build threads a lot of good info and in there for this kind of stuff.
If the mains that come with the boss block don't allow for the windage tray, then how important do you think it is? Does the main bolt kit that comes with the block include the stand off for the oil pickup tube?
I did see you used the gt500 pan and gasket bruce. I will have to re read you thread. What is a half tray? Any info on the rear plate?
