Where you want to put them? In your stock tailight location? or roll pan? If its in the stock tailights then you need to get some tailight fillers and weld them in. Next youll need to buy the caddi buckets and cut a hole so the buckets will fit where you want them, weld them in, do your body work and paint then mount your new lights in the buckets.... And 500 seems steep.... You can get the kit from cando specialites, LED caddy lights, buckets and real GM chrome bezels for 350.00....

If you're nice the guys at can do could make it easier by installing the light buckets into the fillers as they do custom pieces
