Oliver 550 Steering Gear Lubrication Question

Okay, I've searched the archives and found the thread below, which discusses adding lubricant to an early 550 manual steering box which does NOT have a filler hole. That post states "The filler hole is not apparent as it requires removal of the top right hand upper bolt on the steering housing in order to gain access to the passage." On my box, I've removed and checked all of the bolts and can't find a single one that is drilled into the box cavity. Any suggestions on how to add lubricant? Am I missing something? Thanks.

To answer my own question, I reread the manual, found a picture of the filler bolt location, and went back out and rechecked that bolt with a probe and small flashlight, and yes, the upper right hand, 7/16" mounting bolt is drilled into the box cavity. I decided to drill and tap the bolt and add a grease zirk as long as I had the dash removed.
