Hi. Doing the dreaded valve cover gasket swap on a new-to-me 87 Ranger with 2.9. Somewhere along the way, I've lost one of the "moustache" valve cover retainers. Have the bolt, just need the retainer which I assume spreads the torque out a little more broadly. Does anyone know if replacements are available? Thanks, in advance for the counsel. I did use the more expensive Fel-Pro gaskets in an attempt to keep leaks down!
