lift

I have my dirtbike that i always talk about , its dual shock and 37 years old , it is very low to the ground, ive been trying to make mounts , but it doesnt work so does any one know where to buy 17" dual rear shocks or 4" mount lifts PLEASE TELL ME WHERE!!!

I've been working on my 1997 wolverine for over a year now and am finally getting it running right. I was wondering if anyone could tell me how to adjust the suspension and also what should i adjust it to for a more firm ride.
