Men, thanks very much for the info. George, I don't know how I didn't see the washer in the end, must have had an eye closed! I have now got it all together & will start & put it all together over the next couple of days. I have printed off the diagram of the master cylinder, so my sons will have something to help them in the years to come.
I am making a new sound deadening layer to fit under the floor mat, which should also reduce some heat coming up from underneath.
Once again, thanks for the help. The help & advice I have received over the last few years has been great, and I tell friends what a great forum this is.
