Mike, Thanks for the compliment...

3M makes a good double faced tape adhesive for those items that you might buy that don't for some reason come with it. A couple of adhesion tips....:
Clean the area really - really well using isopropal alcohol. Stick 1 side on repeat the process on the item to be attached. Press them together firmly.
Take a blow dryer and set it on the high heat setting and go over the part pressing firmly until the adhesive becomes soft to the touch on the side.
