I had asked them if they would sell the whole threaded body and they said no. I have an option to get bodies made for koni race shocks, but I was afraid their height might be too tall for my goals. Plus I liked the idea of adjustable mounting height vs spring perch. I do not know what I would put in them. It would all depend on how much room there was inside. I think anything from blistiens to koni or even a high end shock. If I am going to upgrade from my HAs I want it to be worth while and something I can run with for a while. I had not seen any diy kits that have that sort of adjustment bodies. If I could find one, I think that is the route I would go. I even looked at the Ceika stuff, but I am waiting on some feedback from people who run them.
