Not sure either, I doubt there is one that has been dine locally. It would be worth just pulling all the info off the 100's forum, print it out, and just go to a trusted mechanic.
He already has the "hi" mode mod (see signature), it is wanting to take it completely out and move to a standard torsion bar/spring change. It's common mod for the AHC equipped vehicles.
Robbie is a Cruiser specialist and will do about anything Cruiser related. He lives out from Golden and is heavily utilized by 'Mud members. He goes by Robbie in the forum. Juane is an expat HDC member now living in Salida. He goes by Juane in the forum but his name is John or Tobascofish or just 'Fish. Juane had Robbie come to Salida to build a hundy for his GF and they removed the AHC during the build.
I realize you asked for someone local but Robbie is the very best and he will come to you. If you decide to bring him here then let us know. A few years ago he was here in Albuquerque for several weeks doing various projects for HDC members.
Coming into the conversation late.....
Yep, Beowulf's recollection is sharp as a tack.
Pulling the ACH system is a matter of locating all the parts and ripping them out. Not technically difficult, just physically a pain in the ass requiring extreme contortions and getting into tight spots. Also quite messy - and whatever you do, do not compress the shocks with the hydraulic fitting aimed at your face!
