(FOUND) WTB 5/16 rear wheel cylinder bolts

[mtull]

I'm looking for (four) 5/16-18 Hex head SEMS bolts for mounting rear wheel cylinders.  Bolt head markings are shown in option 'B' in attached image.

Any help greatly appreciated.

I might have some extras I know they aren't in the best condition because of their location. I can look through my bolts.

Thank you

I'll put these with your rear struts.  Should have more, these were handy.
I thought 5/16" were for front wheel  cylinders?

Thank you @Mr Cuda, those look really nice.  I really appreciate you taking the time to set those aside.

The rear wheel cylinders with casting number 288613 use the 5/16 bolt (I found out today when trying to mount them).  I'm not sure when they switched over to casting number 341776 but those use the 1/4-20 bolts.
