so what is the difference? The length? What is the correct length for a front F3 chassis? Will a TMCC board circa 1996 accept an electrocoupler?

Is the original missing? They work fine with TMCC. BTW you will get a better answer by providing your F3's actual PN. Not the cab number.

6-18128 Sante Fe would be the same by looking at them. But would like to install on a 73-75 b&o which I forget the number of. But installing a similar TMCC set up in that.
OK...The original Lionel electrocoupler as used with uncoupling sections will work with a TMCC board that has support for electric couplers aka electrocouplers. As an example I have a 1950's F3 2343 repainted as a 2344 NYC F3A with early TMCC A powered unit control and early A unit unpowered TMCC sound A unit control, Both support coil couplers. The TMCC boards were added to stripped conventional Locos from the 1950's. The original electrocouplers work fine.
