Thanks for your reply, a friend of mine here in the UK has been in the chainsaw business for 40 odd years and he has an 08S with the kit fitted, he says that they were available quite a few years ago, I see that the brake band, the lever are available online as oem parts so was hoping that there maybe more of these parts around? I prefer the older technology on Stihl and Huskys as I have quite a few saws, regards David.
