I can get what you need.
it'll be $150us plus shipping from the states.
350# & 450# springs come in the kits.
collars are 4" long so you have about 3.5" for adjustment.
comes with everything needed.
For tubes that are smaller in dia then the AE86/TA22/RA21
there are rubber O-rings that slide around the tubes and the sleve fit over those.
Mine fit like a glove. I even had to clean off the tubes to get the sleves to fit.
