1966 plymouth factory disc brakes

[1966 valiant]

Lost a bolt on the passenger side front disc brake. Wondering if someone can tell me what size the caliper mounting bolt is. Don't want to take other one out if I don't have to. Caliper is flopping all over.

Pm me if you need one.
I have factory originals too

To answer your question they are a 7/16-20 thread

That is a very specialized fastener & was rather difficult to obtain until recently.
Get the right one from hemidart67 .

will keep hemidart67 in mind. got the problem solved. the bolt i needed was a 7/16-20 thread inch and a half long.

Great. Someone else posted on that a few years ago. They found a Grade 8 bolt that worked at Ace or Fastenal. It didn't have as long a shoulder or such, but worked fine.

I'm a machinist Bill. Got one from one of our suppliers for free. I just pulled the other bolt to see the length and the thread. Works perfect.
