Chris – You must be very happy to have reached this stage.
One thing to note about leather straps is that there will always be a bit of ‘give’.
This is because you need a bit of slack in order to actually do the buckle up.
In my case, this slack allowed the bonnet to bounce up and down while driving along.
Whilst this was only a few mm, I ended up putting in some extra bonnet locks for my own piece of mind.
Good luck, Paul.
PS
Obviously, I’m a fan of the twin hump style.
