Claim 11:
12. A method for obtaining a shape of a component within a subterranean well with an impression tool, the method including:
providing the impression tool having:
a top sub, the top sub being an elongated member having a central axis, a connector member located at a terminal uphole end of the top sub, and a threaded recess located at a terminal downhole end of the top sub; and
a bottom body section, the bottom body section having a block body, a lead impression block positioned at a downhole side of the block body, and a threaded member having a downhole end threadingly attached to an uphole side of the block body;

threadingly engaging an uphole end of the threaded member of the bottom body section with the threaded recess of the top sub;
limiting axial and radial movement between the lead impression block and block body with a shoulder in the block body and pin that extends radially between the lead impression block and block body;
securing the impression tool to a delivery string;
extending the delivery string from an earth's surface into a wellbore of the subterranean well a sufficient distance for the impression tool to engage the component within the wellbore; where
the connector member secures the impression tool to the delivery string; and

the bottom body section is selectively threaded to, and unthreaded from, the top sub; and
replacing the bottom body section with a replacement bottom body section selected from a collection of replacement bottom body sections having variable maximum outer diameters.
