Intermountain F-unit Coupler

[SD452XR]

All my Intermountain F-Unit couplers are a bit to low. Does anyone have any ideas on how to rise the height on these? The way they are put in there I don't see a way to raise them up. Too bad they weren't to high. Easy fix with a shim. Thanks for your ideas.

What I've found is the screw that goes through the base, pushes the coupler down on the chassis or the base angles down because of poor fit. The easiest way to correct it is to file the bases just a bit.
