I have a set I pulled off my Mistress couple months ago and replaced them because of oxidation, salt corrosion in places, which all looks cosmetic to me, there's a slight little play/slop, nothing major. They are not frozen up by any means and my boat was tooling around with them as of Oct '07, no issues.

The 4 trim rams are all there and are all good (these are worth $$$$ by themselves) and inner plates are near perfect too. All of it needs to be media blasted, stripped, and painted for sure. I'd let it all go for $1200 or B/O .. plus whatever shipping costs.
