This was the easiet heater core swap ever 'cause I didn't help, just supplied the garage/tools!
While he did that I did some exhaust changes on my LX. Any project on a Mustang is easier than a heater core swap!
Does anyone else have to take Dramamine (motion sickness pills) to work on their Mustang? If I go under the car and come out quick I try to spew and can't keep my balance. Heck that's fun!
