Installing gooseneck bushing question

I'm rebuilding the pot assembly on my 520? EFM. The area in the gooseneck casting where the bushing is installed is somewhat eroded (maybe not the best word) both toward the pot and toward the ratchet. What is intact seems to be sufficient because it takes some effort to install the bushing. My problem is I'm not sure of the correct depth to install it. I want to get it in the proper location. Could someone provide me with a measurement, possibly from the flat surface on the end of the gooseneck where the coal pipe enters to the "coal" end of the bushing. I hope I've made this understandable. Thanks in advance for any help.

Use a tool slightly larger than the outside diameter of the bushing. Drive the bushing in with the tool until it meets the cast iron face. The tailing edge of the bushing and the cast iron will be flush.

A piece of 1/2" sch. 40 black iron pipe works dandy for bushing work.
