      A:

      Hi Tony, glad to assist you! This Heli-Coil Thread Repair Kit - Part No. HEL5521-7 is universal and is not application specific. You would have to match one by size to what is on the vehicle that can be fabricated into its place. The Heli-coil tap is a specially designed tap for the 7/16-14 Heli-coil. The size on this tap refers to the Heli-coil size and not the actual tap size. The actual tap size is slightly smaller than 9/16, thus the reason for the 29/64 drill size. Using a Tap Drill Size chart (you can find one on-line if you need it) a 9/16-12 fastener uses a 31/64 drill size; a 1/2-13 fastener uses a 27/64 drill. The Heli-coil tap drill size is 29/64 which is between the normal 1/2" and 9/16" tap sizes.

      Hello Dan, I will be more than happy to help you answer that question. This should work to repair the threads on the engine as long as you have the correct size and are sure they are installed correctly.
