brake line support bracket

Does it need a bolt + nut? Or is it just a bolt?
Lost them after suspension install.
Also what size?

 

The brackets on the leafs or the hard line on the axle? I can look but I think both are just bolts. Think the leaf was an m6 and the hard line an m8 but I'm remembering not looking.

 

Yea the leaf one

 

Definitely bolt only. My pass side wouldn't fit after lift. I had to bend the bracket way out to make room. That one is a small bolt. I'll snap a pic this morning

 

It's pretty short as it threads into that bracket but obviously doesn't hit the leaf.

 

Was a 10 or 12mm socket.

 

thanks!
