After spending a fortune on inner and outer sills and seeing the state of the inside of the jacking points, I have been trying to get some original slide in covers, or bungs, to stop mud and the like from ruining my new ones. However, these do not seem to be available any more, although other BL models seem to be well catered for. I can get a pair for a Morris Minor on eBay for £4.00. I'm old enough to remember when all cars had these, but every manufacturer produced ones with a different diameter and angle for the outer flange.
Anyone know where I might be able to get these, or ones that might fit with a bit of "Whittling". Or maybe best to leave them out and keep it pumped full of cavity wax?
