The SD40-2 in the new Lionel catalog are nice, but...
Maybe one could be bashed into a GP40-2. New trucks (from the GP35?) and shortening, and...
Then again, there is only one guy around here who would try something crazy like that.
Yeah that IS crazy.. esp when an article in a O scale 48/ft issue #173 & #174 mag did step by step construction of one from a Weaver GP38!
