Thanks Dave - think I will fpllow your lead and make my own
I have been investigating this very topic as a possible project and came across this interesting paragraph in Gomog
GoMog - Brake Reaction Bars "It is a very simple installation. I have never seen any indication of damage to the frame through their use. One precaution is to use bolts weak enough to shear in an impact. The Mulberry and Heart of England versions are supplied with such bolts. There is another reason for this. The flexible steel frame and wooden tub of classic Morgans absorb impact forces..thereby sacrificing themselves rather than transferring that deadly force to the occupants. We do not want to add anything that can change that. It saved my life. Lorne"
