Go to a high quality saddler and get one made allow a large area of leather under and around the buckle then go and find the shortest sheep's wool rug you can find cut it into a strip and glue it to the under surface . You can use two buckles if you wish but if you loosen one the other side slips ( I think thats asking for scratches ) . Comb the sheeps wool with a fine comb regular to keep it free of dust etc and when you open the bonnet let both sides of the strap go inside a clean engine bay , wipe them before you tighten them up again . Remove it before you take it to a garage .

It's the old and vexed question of bonnet straps. I know that most people are down on them as a useless affectation and the equivalent of a bonnet mounted scouring pad. But many early and later Morgan's had them fitted and, I think, they look fantastic.
Is the scratching that bad and can anything be done to minimise it? Presumably, the scratched area is covered by the strap? And what do people think of the Simmons alternative strap? I don't think it looks as good as the factory one, but is it less of a scouring pad? [/quote]
