FZR 600 3JH Rear shock issue HELP

[Deerstalker 68]

Hi ,

I put R6 5eb swingarm into my fzr 600 ,swingarm works very well ,but cant get the shock to work, It`s too soft and keeps bottoming out
wearing away number plate ,
I`ve look on internet and found that a gsxr 750 shock would work,but on looking at the gixer shock i noticed that it is about 1 1/2" - 2" longer ,

Will it fit and how would i go about fitting it ?????

Rather than that, it might be simpler to catch up with Penske, Ohlins, Race Tech, Fox etc. and just fix a proper spring for your riding setup/style and keep all your geometry. Dunno, just a thought.
