Fitting the Finder
The best part about using a 160 body is that there is no need to enlarge the mirror post hole. However, you still need to drill a couple of holes and grind to get the finder assembly to fit.
To see what it takes if you use a 110A body instead of a 160, check here.
First, take the finder plate and line it up. You'll quickly notice that only the screw hole on the left lines up. Drill a new hole for some extra holding power, and then drill a larger hole in that notch of the plate.
The larger hole will hold the plastic housing. Without this hole, the housing will be kind of flimsy. Make sure the hole is large enough to fit the screw through.
If you haven't noticed already, the 900 finder plate does not have a place for the leather strap. You need to remove a small part from the 110A's plate and add it to the 900 plate.
Put the finder assembly onto the camera body. Notice that the moving parallax frame gets stuck here. Grind this down flat.
Before you can assemble the finder completely, the plastic housing and plate need to be trimmed for the newly mitered edge.
Tape the plate to the plastic and correctly line it up with the edge. Mark this. Cut along the mark through both metal and plastic.
But now, you have this nasty ugly edge.
Time to get to work.
