What I think you are looking for is a GM Buick B Parts And Illustration Catalog it shows the part and the part number , I had one for my other wagon a 93 . I've been looking for the 94 version for over a year . Another option would be the catalog that insurance adjusters use again it shows the part and number and the estimated time to replace /repair that part .I have one for my Solstice that my friend who is an adjuster gave me years ago but unfortunately he retired and I don't know how far back they keep these things .
