Hi Todd, Unfortunately, we do not have that data readily available. I have checked resources based on your given vehicle application and it came up as stud size- 14x15b. That may not be accurate but you can confirm this with your dealership by providing your complete VIN number. Still, this wheel hub assembly is a confirmed 100% fit for the 1993 to 1995 Chevrolet Camaro, Base, 6 Cyl 3.4L / 1993 to 1995 Pontiac Firebird, Base 6 Cyl 3.4L / 1993 to 2002 Chevrolet Camaro, Z28 8 Cyl 5.7L.

Hi Tyler, No, these are for the front only. To check the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.
