Replacing a part by its hole pattern

On a part like this the centre distance decides whether it lands on the holes that are already there: 70 mm here, with a hole diameter of 10 mm. Measure the part you are taking off across its fixings, not only its outside dimensions, since two parts of the same 100x115 mm size can still have different hole spacing. Look at the material around the old holes while you are there, because a bolt that has been working in a slightly oversized hole leaves marks worth catching early.
