Hi Anthony and welcome to the LOC, we are a friendly bunch and some of us even know how to pull them to bits and put them back together again, with of course the one bolt and washer left over.
I cant help with your present queries but I'm sure someone will be along ASAP.
We recommend you spend a couple of mins looking over the rules of the LOC, we will be asking questions later
