A service manual is invaluable for things like this but if you don't have access to one try this website as it may be of some help:
http://www.corvetteamerica.comClick on the "looking for something specific" icon, then on the new page enter the year of the car and a keyword for the area where you are looking for a part (eg: interior). Once you do this and get some options if you click on the parts listed some diagrams are given.
Hope this helps - probably the best I could do. Anyone else?
