Lower the 04 Softail and change the rear fender if necessary

Hi, I took a few pictures about the current situation and have a few questions: – Wanted to buy a Müller lowering, because it is still a bit too high for me. Is there a spring travel limiter or something similar? – actually I would like the “styletto hedge” better, but then I probably have to cut off the struts, right? The mW are removable only with later models. – can I just exchange this seat for a like for example with the picture with the “stylet to”? The rear light should be soft anyway, the Kellermann “DF” wanted to mount turn signals with integrated rear and brake light and then make the mark on the side next to the wheel… Then I would have the current Fender anyway “clean” and new paint. I just don’t know what pays off and what didn’t want to spend any sums. Thanks for tips Greetz Ron
