Roo,
Since you’re obviously an expert, please share your thoughts on how to correctly do this with regards to the correct height and prototypically correct spacing especially where the newer Atlas cars which have the .050” tapped bosses to contend with. Anyone can slam Kadees on any Atlas car, the trick is to try to do it while respecting the above parameters. The point here is to flesh out ideas, techniques/work-arounds so as to triumph over a manufacturer’s not-so-secret agenda of forcing us to use only their barely adequate couplers.
Please, I’m all ears.
