Ford changed the way the heater hoses were protected against the firewall opening in 1970. In 1969 they flared the hole towards the engine to soften the edges and used dark gray butyl to make the seal waterproof. In 1970 they simply used these rubber grommets. This improvement is just one of hundreds made to the 1970 Mustangs.
Take a look at the third picture to see what these grommets looked like installed on a un-restored Mustang
