I didn't do anything to the T bar. An early plan was to file away some metal at the back of the T bar to allow it to pulled back further but without altering the stop towards the end of the car, a trainload of cars would just pull on the spring and the gap would be unchanged.
That is an option though and could be done without disassembling the car.
Joe, for me this is just an extension of growing up with HO in the 50s. It seemed then the ideal was to build everything yourself from rolling stock and structures to laying track. Brass engines were mostly assembled kits that had to be taken apart to run right. Very little ready to run unless you were willing to sacrifice detail. Not unlike todays 3 rail.
