I recently installed a set as well while I was doing my clutch job. I only did the front ones so far but I will do the rears in the coming days. Like others have mentioned, there's no markings on the collars. I watched a YouTube video where Chewerks was installing them, and they pointed out that the collars are marked. I did my best but could not find any identifiers on them. For such a simple part it gets rather confusing in a sense that the instructions mark the collars as F1-3 and R1-3 like they're all different, but as mentioned, there's only 2 different sizes for all.

One other thing I will note is unlike the videos I've seen, my collars did not just drop right in to their respective holes on the subframe with a nice clink. In fact most of mine only went in 2/3 of the way by hand, they had to be drawn in the rest of the way by tightening the subframe. At first I was concerned that I had installed the wrong one in the wrong hole, but after literally test-fitting every single one and determining that there were indeed only 2 sizes I concluded that they were definitely in the correct spots. I'm assuming that they were maybe machined a little too large? Or maybe the holes in my subframe were slightly small? Regardless the bolts made them flush without much effort. It was just weird because in every DIY video I've seen they tend to drop right in with ease.

Here's some pics of the collars before I installed them, quite certain these are authentic.

Tackled my Spoon Rigi Cola over the weekend when I did my clutch replacement with these handy videos from @Soviet
