well I'm not much help, mine came apart so easily it wasn't worth taking pics.
I turned the shaft by the allen key and the whole gold plate turned in the strut. Then I just slid them right apart no problem. Mine did not have the tubes swaged or anything. Once the strut is assembled there is no need for anything to really hold that gold piece to the tube since the strut and the nut on the bottom holds everything together.
After the strut slid out of its yellow tube I saw the 3 piece bumpstops. I cut one piece off which close to an inch and called it good.
If yours is swaged just take a chisel and knock the gold plate off the end of the strut tube. The strut will then be free to come out. You may have to hit it on 4 sides since the tube in the pic looks swaged together. you do not have to remove the plate from the strut rod. Just cut the part of the bumpstop using some side cutters. Be careful not to scratch the strut shaft.
