MoW saved the day. Brute force won out without collateral damage. The cab interior and the very large headlight, marker light and ditch light array mounting structure is an extremely tight fit and I may have to do some file work to get it back in. There is no sign of melted lamp housings or other such defects.
My only disappointments were the MTH instruction manual, which misidentified the body mounting screws (I didn't believe them) and the amount of grease that had escaped from the gear boxes, covered everything in the general vicinity and took hours to remove.
Thank you for your advice. You gave this poor trackman the courage to go on to victory!
