Help me... I think I purchased an oddball 70.
My site glasses are mounted to the manifold by a heavy casting held in place by 8 or 9 bolts. When removed the site glass is held in place by a spanner type of nut. Behind the spinner is a dome shaped housing which is only on one side of the manifold and not the other. My friends have 70's series pumps and they do not have this style. Can anybody help!!!! Thanks
