Question Mid Cabin Cover question

My in-process RV-8 is in need of a single 3 1/8" Instrument in the location of my Mid Cabin Cover. It is a fuel injection controller, and not typically required during flight, so I am ok with the lower location. (and I have zero panel space available)

There are 3 ways to solve this that I can think of:
  1. Take part F-880C-R-1 (Mid Cabin Cover on drawing 68A) from an RV-8A, and cut down the aft portion, and fit it on an RV-8.
  2. Design and make a similar part to the F-880C-R-1 myself. If I do this, I would probably rotate the face of the instrument about 30 degrees toward the pilot.
  3. Construct an angled "box" that would sit on top of the existing part F-881-1 (Drawing 68) with a hole for the rear of the instrument.

My questions for this group:
  1. RV-8 Builders: Has anyone done something similar to #1 above?
  2. RV-8A Builders: Can anyone tell me the dimensions of the rear angled face of F-880C-R-1? If it isn't at least 3.8" it won't work for my application.

Here is a very rough mock-up.

or here if that link doesn't work: http://tinypic.com/m/k51iko/4

Default Covers

I did something very similar to this. Mounted fuel gauge above fuel selector at an angle. I ordered a new 881PP cover since the fuel valve was already installed and need to be redone. I looked at 8A plans as well and ordered:

F-8113A-L-1 mid cover and cut it down
F-8113-B-R-1 and F-8113-B-L-1 side covers. I did reinforce the front plate with 0.063 for an instrument.

Can send pics if you want.

Default Fiberglass

I made something similar on the left side FWD of the fuel selector switch. I made it out of fiberglass. I started with cardboard cutouts, then used those to make a mold out of pink foam. Glass makes it real easy to get the angle/position you want.

Aaron - Would you happen to have any pictures of either the process, or final result? I'd love to see them.

Default Fuel pic

Here is mine. Might not work for you as the instrument penetrates the 881 cover.
