Reico Titan Electric Jack Crank Cap Alternatives?

I ordered the jack refresh kit from Reico Titan. The kit comes with crank caps which are the caps that go over the hole where one can use a socket to raise/lower the jack manually in an emergency.

The caps do not fit on my powerheads.

I've contacted Reico Titan but communication is slower than my needs.

Does anyone have another nice looking solution on how to cover that hole?

My electric jacks were made sometime around 2007 andcame on the camper if that matters.
