[Elecraft] OT: Begali Traveller, Replace Finger Pieces?

[Kevin - K4VD]

I purchased the Begali Traveler from a list member and love it. I ordered
up a set of aluminum finger pieces but not sure how to install them. I'm
concerned I'll unscrew something and bits and pieces will fall out... NOT
mechanically inclined.

Has someone here replaced the Traveler finger pieces that can give me some
quick instructions?
