Thermostat Housing Leak

When I read the title for this thread I thought "he`s got one of those Chinese chrome housings". I bought something from Mancini years ago and they gave one to me free. Now I know why. After sanding and sealing and cussing I gave it up and bought a factory replacement. The originals may still be available from a dealer, (that is if you can find a dealer still open). I`ve seen the chrome necks with the O-ring on Ebay and haven`t heard anything bad about those yet.
