i know you have technical drawings and this is your specialty, robbman, but to try to make something in Z scale that doesn't yet exist will never yield a perfect result, until the manufacturer claims to have made such.
i count 10 doors of similar configuration from the end of the air filter section to the beginning of the radiator fan section -- on both engines. i count seven door of similar configuration under the radiator/fan section. grills are different and fans are different, but the basic layout seems very similar.
there is a marked difference in the air filter sections (behind the cab) of both locomotive types. that's where some more work might be done. but in attempting to apply what limited parts he has available to approach a general outline, i think joe has succeeded well. it looks MORE like a GP60 than anything else.
maybe one day we'll get an exact Z scale GP60 with all the rivets, but even then the N scale manufacturers can't apparantly make a GP40-2 that is actually correct, as you've pointed out elsewhere.
i don't think joe is pretending at all to speak with technical clarity, or as a representative of MTL, and it's unfair to interpret his work on the GP60 as such. He's only attempting to model a facsimilie of a favored locomotive to search out the possibilities. it's kind of like picasso with a pen in his hand -- i don't think he intended to create a work of art every single time; don't you think sometimes he might have just meant to doodle first.
