Mast step base question

I’d like to replace the base of my mast. I have a replacement base but as I look at the current base it appears to have a rivet securing it to the mast whereas the replacement (pic below of the one I have on hand) has no holes to accommodate a rivet. Does the replacement just press-fit? Any special tips or guidance? Thanks!

Castings are not pre-drilled. You will press in place and then drill for the rivets.
