I understand your angst, since I have been a contest model builder all my adult life. I also fell foul to mis-information building my replica Mancha A minemotor, the front coupler box is 1" too wide. I had assumed it was the same as on the later B model as well but on comparison with pictures side by side of the original and the replica the difference is glaringly obvious, and now I am constantly annoyed by the overwidth look.
However no-one else even noticed the difference, even when shown the photograph of the original, and I guess
in all reality, no one cares.
Como will be the same,
in all reality, no one cares.
