Matt, at my age laying down under the car and trying to get the bales loose from the MC and then get the lid off, only to crawl back out to lift the carpet panel to access a small, round access port just doesn't compute. Besides, the lid on the MC just barely clears the underside of the floor, so I'm not sure I could get the bales loose and out of the way from underneath. I'll check it tomorrow, but my thought is that trying to pull the lid on this one would be a PITB.
On the '33 I needed access to both clutch & brake MC's so the removable panel is maybe 8"x10". For this one I'll just need a nominal 4" x 6" or so (if I position it accurately). Also, last time I followed a recommendation to cut a piece of flat fiberglass out to form the "lid", using the piece removed from the floor as the "guide", bonded to the underside of the lid. Even with the edges rounded it's 3/16" or more thick. This time I'll cut out the hole using a saber saw with a fine tooth metal blade which takes a very narrow kerf, and will then bond the piece cut out to a piece of 16 gauge sheet metal sized for a nominal 1" rim around the hole for the lid. It will be virtually invisible under the carpet.
