Am curious if there were any issues in the field with repairing the RR vs Packard versions. I read somewhere that when Packard first started production engineers had gone thru the plans and converted everything made in Detroit to use American thread sizes because the original RR designs had used mixed such as Whitworth, British Standard and Metric threads as well as some actual pieces being in metric and others in something else. If that is true I could see someone in the field trying to cram a wrong part or bolt in somewhere or messing one up by using the wrong wrench.
