Manitou Swinger X4 7.5*2

I bought this shock off another user, who listed it as 7.875*2.25. Those arent the correct measurements, so of course it doesnt fit my bike. I paid $120, i would just like to recover some of my losses. Eye to eye measurement is 7.5". Stroke is 2".
Has SPV platform adjust, rebound and preload adjustments. there are a couple small knicks on the piggy back can, but all in all it seems to be in good shape. I believe the bike it came off of was a 2006. I have never ridden with it, so i dont know what else to say...
