plugging oil fill tube hole

The manifold I will be using has a hole in the front for the oil fill tube but the location of my alternator and the fact I am using a water pump riser I think will not allow room for the tube. Has anyone plugged this hole and if so what did you use? Thanks

 

Depending on size, i would guess NAPA has a freeze plug that'll fit. And.... Go STEELERS!

 

just use a freeze plug.

 

I had one on my 312 and a small freeze plug didit fine. Not the first time though. Funny the things ya learn.

 

Freeze plug sounds like a good idea. Thanks for the responses.

 

I second that!
