finally had a chance to break open the 555 transmission to install a moly bearing plate i bought several years ago. couple questions (complete newb at this).
the new moly is on the left. the original plate is on the right (have no history on what, if anything, was done to this transmission by previous owner).
1) i expected more of a "difference" in weight/look. could the original actually be a moly plate already?
2) there are some differences between the two (circled in red). the moly has a much bigger hole in one location as well as the original had some machining done (a slight depression) between the two big holes.
are these differences anything to be concerned about?
