Here's the problem. The shroud end has an aluminum plug with a groove to accept the
shroud, then there is a cap to retain the shroud in the groove. The plug and
cap were connected using two stainless screws. Guess what? The corrosion
was so bad I had to hacksaw stuff to get them apart.

Use zinc-chromate paste to prevent galvanic corrosion.
Here in the Netherlands it goes by names like "Duralac", "TefGel" or
"WeiCon". Every decent rigger is familiar with it.
