Merc 120 Trim Solenoid

[Bdt 1967]

Hey yall, I am looking for some help, I need to find a trim solenoid for my 80 Merc 120 pre alpha. The up works fine but the down is no good. Do any of yall know what one I need? I would take the cover off and find the part number but the boat is in storage right now.
