One of my old struts was an aftermarket universal strut of unkown brand that was installed on my car after someone hit the front wheel in a parking lot. Absolutely no way to make this housing work as you can see here what the end looks like after I cut it off. First of all the tube diameter is different the whole way down and they also have this strange end that was threaded on. Just no way for it to work which is a shame because I ended up cutting up one of my FE5 TC Cobalt strut.
