Dimensioned of a Transformed (Copy) Part.

I am working to make a Fully paracentric workbench model. This bench has a top and a bottom shelf that are identical. So I "transformed" the top structure down to the bottom shelf. The problem is the bottom shelf is 3.5 inches and the top structure is 6 inches. So, I did another transform to scale the bottom shelf along the z axis along 0.583, which makes it equal to 3.5. The problem is this breaks the parametric aspect of the design. When I change the variable #STDboardWidth from 6 to 5, everything changes as expected, except for the Scale of the transformed shelf. Since it is a scale of the top structure it undersize the width of the shelf boards. Below are images after I change the board width from 6 to 5.
I don't want to resketch and extrude the entire shelf structure just to size it down to 3.5 in. I am pretty sure that there is a way to do this, I am just ignorant on how it is done in Onshape. Is there a different way to copy and paste parts or is there a way to set a dimension for a transformed part?
Any help is appreciated. HERE is a link to my design if that helps.

Ever used the Move Face and Replace Face tools? Scaling isn't the best way. Check this out. I made a plane that's 3.5" offset from the shelf bottom, then used Replace Face on the top faces of the boards. This way it doesn't matter how big the top shelf is. The lower will always be 3.5". The top shelf could even start out smaller and this would work. Realistically, you don't even need the plane, since Replace Face has an offset setting, but it might make the model easier to understand. https://cad.onshape.com/documents/be95079c1ae2590dce5f8de4/w/fef3d87f3df8e933d54e4d5a/e/a36f727e1bf0d404ff319e2b
Brilliant. I haven't used any of the face manipulation tools yet. I ended up using the move face instead of the remove face tool. Now everything is perfect.
Glad to hear it! both of those tools are super handy
