Ping Pong trucks

I bought a couple of Funaro and Camerlengo ping pong coaches. They don't come with trucks. I've sent several emails to them asking what truck they recommend and have not received an answer. I'm hoping someone on this forum can help me.

Thank You,

Tichy makes classic Ping Pong trucks. One caveat... the bolster is really low. I've found an assembled Kadee coupler box provides about the right height. Yeah, it is weird.. but it works. They told me it was a manufacturing problem but they got like a huge quantity of them and can't really reorder/redesign.
