The oil fill for the FNR box has me confused. The only plug I see is high on the front of the case. So do I use that or can I use the vent tube fitting on the top which would be a lot easier. Unless there is another plug that I'm missing, ( and I stared at it alot), I'll fill it with 3.5 oz of 75-90w gear fluid.
So, am I all messed up here or is this at least somewhat correct?
