What did you do to your van today?

[trevskoda]

The reason the nyloc was used is because I dropped the dome nut which is now down a hole hiding. As soon as the nylon touched the screwed rod it then screwed the rod further into the rivnut on the baseplate.

I would have used a longer bar with a double bend at side of the battery which would have also stopped the bow in it, yep 2 days ago i lost a useless bracket down the side of the engine never to be found.
At least you got the problem sorted.
