Came to the discussion late
Only advice I have is with any tray or pan, be sure the main cap can dump the oil. You'll see the oil dump slot on the cap, there used to be some pans, gaskets, and.or trays that could block that dump and the main seal ends up being pressurized.
I haven't seen one in a long time, but every so often the pics come up on the FE forum. Look closely at the rear cap and you'll see the oval dump, just be sure the tray, gasket, or pan cannot block it

Note the notch in this original style

Note that there is no notch in this random internet picture . It doesn't mean it WILL block the dump, but be sure to check
