Hi L, This mirror does not have the chrome cap at the back. I do not have the bolt information readily available. That detail is not mentioned anymore since fitment selection is guaranteed by simply selecting the correct (complete) year, make model, submodel, and engine size of your vehicle. Type the part's name in the search box. 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.
