The bellhousing between the engine and gearbox has a few openings in it. This must be a somewhat universal bellhousing, since there are openings for a mechanical clutch fork on both sides. I can also see the flywheel on the N/S. I am waiting for a starter to come, so I am not sure if there is a gap on the O/S. Covers need to be put in place to prevent stones and debris coming in contact with the flywheel and clutch.
I am going to use aluminium to make up covers. I have made up one so far, and have fixed it to the gearbox by drilling and tapping out for M4 button head screws. I used a hoover to keep down on swarf. I have started with the easy one, and the others will require a little more sculpting..
