Front disc brake kit came with recommendation to change steering knuckle fill plugs to a flat version. Does Kaiser Willys sell these flat plugs?

Willys Jeep Parts Tech:
That a local hardware store would have to provide for you or Napa.

I see in the description that there are two required. I only see one on the steering knuckle of my 1951 M38, the fill plug. Is there a second plug, I am looking for a way to drain the knuckle.

Willys Jeep Parts Tech:
2 required per vehicle. 1 per knuckle. Thanks!

80/90 weight grease goes into knuckle? Thx

Willys Jeep Parts Tech:
Yes, we use a straight GL4 if you can find it.
