Default Looking for a bolt size

I am looking for the bolt that holds the the bracket so that the fuel lines get secured to the fire wall... my car is missing both the bracket and bolt and I would like to get these secured. Please let me know the bolt size and pitch because I can not find this information anywhere.

here's a picture of the hole I am looking for a bolt to fill

Sadly it looks like that used to be a stud but got torn out. Here's a photo someone took for a fuel filter replacement how-to:

In the snapshot supplied in Post #2 the male thread is an M6X1. That doesn't have a direct correlation to what you might need to adapt something to the car. Your snapshot with the Adel clamps you chose I'd think there's certainly a more desirable choice. For a stud I'd think there's also several potential choices.

If someone had a late model salvage case the stud would likely be very easily removed.

I just want to know what threads into that hole so I can buy a bolt.... I plan on using the clamps I have now as all the wrecking yards that are local to me never seem to have any corvettes let alone C4s

Buy an M6 'Grip Sert/Time Sert' or similar and then just epoxy it into whatever diameter you need to bore the 'demolished' hole.

'SHOP LOCAL'

This isn't where I'd shop but there's some good dimensions and images.

It doesn't actually need to be M6 - what ever is appropriate for your Adel clamp choice and the 'demolished hole'. Most any 'LOCAL' will have several options.
