Hey folks, removed water pump from 83 GL. Need new mounting bolts and can not find them anywhere. Looking for help on where to buy replacement mounting bolts. 

 

The ones that came out are really rusted and don't trust them to go back in.

 

Any help is appreciated.

 

 

parts wanted forum here?

 

They're probably a standard 10mm head M6x1.00 thread/pitch bolt.  Just need to know the length and grade and you can: 
 

A.  buy them from any supplier of bolts

B.  use another Subaru water pump bolt, or others, from EA81....maybe EA82/ER27's?

I always just clean mine with a wire brush and chase the threads on the bolt and in the block with a tap and die. Cover it in a little anti-seize and reinstall. Never had an issue. They don't torque very tight.
