Patrick's setup is identical to mine and I have fit the turkey pan and a long-oval with no problem. EDIT: I had to do considerable work to the bottom plate of the long oval to get the AC assembly to clear the trailing edge of the hood, but no problems with engine component interference.

It sounds as if your tank does not have that integrated 3/8 inch spacer - if you got it from ERA, it should have had it in place. If not, you'll need to fab or find one.
