I think I've asked this before but don't recall any solution.
I'd like to convert a bunch of BLMA (and now Scale Trains) cars to the TSC system. I've had extremely good luck with the new couplers and love the lack of slink.
But I'm not going to mutilate those cars to do it.
It should be a relatively simple thing, but putting a TSC into a standard coupler box easily just ain't there.
When you simply replace the whole coupler box assembly it's easy-peasy - but to do that I''d have to cut off the old box and I'm just not going to do that.
Any help here? And thanks and stay well...
