Check out El Fenix auto repair off 17 in South Phoenix. A friend/co-worker recommended him to me to have my flywheel machined on my 60. He works on a first come first served basis, but got me right in and had my flywheel done in around 20min. All he does is rotors and flywheels all day, specifically for all the truck/heavy equipment shops in the area. He’s a super nice dude and only charged me $30. Local Scottsdale/N Phoenix shops wanted $100 or more. Please keep him in mind!
