One thing I have noticed about my tow-bar, which is a Volvo original, is that the tow-ball assembly bolts to the tow-bar with 4 bolts as opposed to the usual 2 bolts.
Both my cars have Volvo tow-bars and they are the same in that respect.

And, guess what, my stabiliser plate is the type that uses 2 bolts to mount so will have to do a bit of thinking about how to overcome that problem.
My '76 244 had a Witter tow-bar.

I might have to have something fabricated for that unless there are any suggestions here.

Good to be re-assured by your towing experience Oily of a Lunar 500-4 with a 240. Thanks.
