User that manufactured an adaptor 02gf74 I think it was linked to XP8 so search author 02gf74 and XP8 should bring it up.
Regards corrosion on the shafts, any imperfections in the chrome will allow the shock to lose pressure and will require a new shaft from Noleen J6 in the states, they won't send the shaft on it's own I've tried.
it may be possibble to get it rechromed but this again is a lot of messing about with an old shock.
Ahhhh on the shock, i was looking all over the forks and couldnt see a thing with regards to corrosion, apart from the Elastomers appearing to be as tough as old boots my forks are in pretty good condition. I am looking at doing a spring conversion on both front and rear and hopefully the Noleen variety as they seem to get good ratings over the Risse shocks, i am not sure how much is true of this as i have found things like suspension tend to come down to personal taste. Once up and running i will update my Proflex build thread
