Rear brake hose to differential bolt thread pitch?

[fly_25]

Seemed to have lost the bolt. Does anyone know the thread pitch of the bolt that goes here? It's for the brake hose. Thanks everyone!

Catalog says it is a GM part Number 15630743. Poking around on the internet says it is 5/16X18X1 3/16 flange head bolt.

Thanks! I've got a 5/16 bolt here somewhere, I'll check it out tomorrow

That's what I got as well. It's not just any old bolt, though, it has an extended shoulder on it. 8633207 and 1239146 are other numbers this bolt has.

Luckily, AMK has this bolt under p/n B-13963.

Interesting! Maybe so you don't over torque the bolt and crush the brake hose fittings

ACE Hardware has the Allen head ones, might have the hex head.

McMaster Carr has all of them, Grainger too.
