Lip up, groove up??? I assumed I would go to the truck and it would be obvious, but it isn't. I got the gasket from Carter's but it has the Steele rubber logo on it. I'm not sure if it is just ANOTHER ill fitting chinese piece of junk or what,
if it says steel on it, then you got a steal of a deal and its the real deal. lip up, the groove fits in the channel. you must remove the vent to get it to go in plus remove all the crap that been in there for 50+ years. at least on my trucks i had to. while your at it look under the dash where the seal goes and look for rust runs and address that too.
