Re: Heli coil
7/16-24, that's an odd size isn't it? UNS? I see only 7/16-14 and 7/16-20 at McMaster-Carr.

There were different pitch sizes between 28/29 and 30/31 but they were all 5/16". What stanchion do you have there? A lot of these old cars have had the Rube Goldberg treatment at one time or another. |

Re: Heli coil
Unless it is a special bolt/head I would use the standard pitch heli coil and use a different bolt.

Re: Heli coil
5/16 X 24 UNF helicoils are available from a lot of sources. The kit has all the stuff you would need unless you just need the coils. Coils are available separately too. Many chain auto parts stores carry them and there are several brands.

Re: Heli coil
You need the tap and installation tool which come in the kit.
