I was at my local Pick N Pull the other day when I saw two trucks, an '80 and '73 both with 14b rears. Both of them had holes on the diff cover near the center. Is that the drain plug hole or did someone put them there. It was odd because both had them. They looked like bullet holes. Is this common or what??
<font color=blue>My 14 bolt doesnt have that. That was probably done by the yard so they can remove the cover and count the gears. I have seen a few yards that do this.</font color=blue>
If they are holes, then as long as they didn't get filled up with rain water they should still be OK. I would pull the covers off and have a good look before buying though. If the yard put the holes in the covers surely they wouldn't mind you pulling the cover for a better look. Check for broken teeth, any sort of shrapnel or rust on the gears. Rotate the assembly and make sure it all works smoothly. If it checks OK lowball them anyways and re-fill it and just add a new cover.
