Can someone show me some pics of the block offs front and back. Are they just flat on the back or are they hollow?
If I remember right the inside of the blockoff plate has about a 1/2"-3/4" hole plus 2 mounting holes. I think mine also has an o ring to seal around the inner hole. It's a very simple piece and if you know a machinest they should be able to make you one but I doubt it would save you any money.
