I just finished the last 2. One had a post and one had a plate part. The one with the plate didn't just set on a slot it had a forked piece - that went over a screw. I don't think I have seen one like that before. The dials aren't great but they do work. I think I like the clones with the post built into the face plate for rebuilding.
There is a lot of variation with the tension springs. They vary in size and shape. It may be trial and error to see what fits and works the best. I do know some rub. Some get stuck and have to use a different size. It may be what came with the machine but it may not be right - blame it on IGOR. Igor with pliers in his hot hands bent a spring... IGOR bent a thread guide at the top of the plate. IGOR cross threaded one of the nuts. IGOR oils tension pins with 3in1 oil maybe... IGOR puts thing back in the wrong order and facing the wrong way.
I hope this has helped somebody.
