I came in on a Friday morning appointment for an oil change, recall software download, and to install a set of valve extenders on my dually. They charged me $30 for the install, but did not do the installation. They said to come back Monday morning and they would install first thing. So I came in Monday morning at 7 and Steve said less than an hour... Two hours later, they brought the truck out. I noticed when I got home that 1 extender on each side did not have the lock nut to hold it to the bracket. Total bullshit - wasted my time and didn't care.
