Hey Bricksters -
I've got a leaky(very small) rear axle differential seemingly coming from the refill plug. I think I've seen references here where there's an included washer, but in fact mine has none. Also, the bolt shaft diameter is larger than the bolt head itself. Does this sound like the correct bolt? Here's a half-ass pictorial:

If this is incorrect bolt; where might you guys suggest I get a replacement?
TIA

    There's no washer, and it sounds like you have the correct plug. It's tapered, so as you tighten it, it seals itself. If it's tightened correctly, and it's actually leaking, you can use some Teflon tape on the threads.

    It has tapered (pipe plug, as Fixed Login Guy said) threads which result in an interference fit as you tighten it a few turns. Make sure it's really tight and if it still leaks, smear a little plumber's pipe dope on the threads, taking care that none gets into the diff. That should do it.
