@H1000 posted:Another question for you Jon. MTH used to include a square plastic bushing that went on the tender post of the wireless drawbar, I've only seen this part on the earlier PS3 steamer but it seams to have disappeared around 2016 or 2017. It seemed to help keep the load of the consist off of the the electrical connector and on that metal post.
They are still available. I just ordered half a dozen. FB0000037
