Default Water pump

71 small block pump leaking slightly. Car has sat for 4 months. Could it just be the seals drying out or do I need a new pump? Doesn't look like it is coming out weep hole, instead it appears to be leaking from seal against block.
Opinions on pump replacement or should I just do gaskets?

Try tightening the four mounting bolts first and if that doesn't work then replace the gaskets.

Cheap as pumps are, replace it if it needs gaskets. Why put an old pump on when it has to come off to change the gaskets at the block. The shaft seal will leak a month later on the old pump! Trust me.
