circumvent the issue.
Can't quite follow on that one. What do you mean by "mirror images"?

Hi All,
I’m currently working on combining a 5061A chassis with a 5061-6077 beam
tube that I acquired and I have a few questions I’m hoping this group can
help me with. As background, my 5061A is a later model with serial number
prefix 2506A (originally built with options 001 and 004). The bea
