should change out the rubber engine mount bushings only because they have

Some people change these at every annual inspection. They are dirt
cheap.

Some are dirt cheap. Some aren't. There's no way to tell without
getting some quotes. The Barry mounts for an O-320 are $125 each,
genuine Lord mounts can be $160 or more. That's for each mount;
multiplied by four, it starts to add up. The O-200 mounts should be
less, but won't be anywhere near as low as the $4 rubber used in the
A-65 mount, for example.
