On my 46 I cut a new hole and folded the edge over with a ball peen hammer, used a 5 or 6” round SS wall clean out cover (plumbing) with a 1” wide metal strap under it the center screw tightens into ( visible in the photo if you look for it under the lid). The hole is bigger than the stock one so I can just get my hands in there to open and close the MC lid.

Keep in mind with a remote reservior you loose the rubber seal inside the lid of the MC, that seal keeps fresh air out of your MC, which is a good thing for fluid life…
