I have a buddy who was kind enough to give me his unused rear shock--as he upgraded his new bike at purchase. The length and stroke are exactly the same, and the shock looks like it's going to be a perfect fit--except that my old shock's screws wont pass through the new shock's "eyes" as the new shock is smaller. I am probably getting the terminology wrong, so please accept my apology. Is it possible to change something to make the new shock compatible with my frame? The space the eye fits into is the same, just the diameter of the "hole" of the eye itself is different. I was just wondering if its possible to switch out the eyes or something. Please forgive my ignorance in asking such a dumb question.
