All tools and parts present and accounted for...Yet another HoleSaw purchased. I am getting a collection of these.
Just about there look right? I did this by eye..... Will it work?
Yup, Hope that is the right place

Whilst trying to fit the back box on I realised that none of the 3 sets of screws supplied were suitable for a panel van and were all too long. I have ordered some new stainless steel ones from screwfix so this job is also on hold.
