What Truck/Coupler Combo ?

[old409]

I have 25 Bachmann Peabody N Ga., 4 bay hoppers. These have been done for Bachmann by several different manufactures And have different truck mountings. I'm looking for a replacement truck/coupler combo that would come the closest to working for all  the different type car mountings.
Before you get on my case, I'm 83 yrs. old, poor vision, shakes and a lot of other ailments.
I have a lot of N Ga. that I want to fix up for the Grandkids. Thanks for any help you can give me. This all used to be automatic.
