laz57,
The NWSL gears for the Niagara are listed as such on their site. I have purchased both for replacement, although I have not experienced problems with mine.... yet. I did replace the u joints with stainless as the original gave up when pulling 12 NYC scale hvywts. Also, as Duke mentioned, I had to re-affix the tires onto four of the drivers, the ones that were/are pitted. I have a post earlier in this thread where I, like Duke, have listed the part numbers and costs. The u-joints I installed are 4mm and stainless steel, easy to change out and work great. Good to hear of the positive impression report from the tech doing repairs on Duke's Niagara, some encouraging news.
