Top product. Of course they only come in white, but I resprayed mine Candy Glory Red.
Note you do really need the bolts because they are quite a bit longer and by the mount's design, the bottom ones are longer again.
You have to live without the flexible rubber insert, but the mounts are the duck's nuts. It's only a matter of minutes to remove them if you need to, provided to put a plug in the positive wire. To earth goes under on bolt using a washer-type connector.
