I took a pair of tinsnips to the gearbox cover on my car to provide access to change the reversing switch - which gave access in about 10 mins. I will make a small plate to fit over the hole when I'm finished.
Yep, I did the same. I have a hole and panel for the reverse switch, one for the 90 degree speedo drive, and one for the speedo drive gear on the other side.....
