INTENSE-Racing.com: INTENSE Supercharger Coupler Change Kit

For options on purchase, but as with ^^^ likely the coupler. search bar at the top, "Coupler" and you should get pages, google replacement and you should be able to find a "how-to". Very easy.

Only recomendation is USE GLOVES!!! I cannot stress this enough. If you have a female companion and want to touch her for the next couple day, use gloves. The SC fluid will soak in and hellfire and brimstone won't get out that smell.
