Rear diff vent hose

[flat landah]

Hey guys first time posting here so excuse me if this has been brought up before.

I decided to do the gasket on my rear diff on my 94 k1500 stepside, and like an idiot I didn't check to make sure the plug came out first... So I did the gasket and cleaned everything up and of course the plug didn't want to hear it. I tried for a while to get it out and all I got now is a stripped plug.

The big problem is that I'm away from home right now and have to drive 500+ miles tomorrow, and none of the tools available here to get that plug out.

So as a last resort I filled the differential through the vent tube. I got the 2 quarts in there just fine, it just took a long time.
So my question is, is there any unforeseen problem that I could run into because I filled it through the vent?
Thanks in advance for any answers I get.

My plug wouldn't come out either, so I bought this. It has a plug in it. I've always tried to get the plug out first before removing the rear cover.

I'd say as long as you got two quarts in you should be okay.
