Vitaloni baby turbos on a bus?

[kra710]

I was wondering if anyone has seen this, Im getting my bus painted right now and before she gets out of the shop I need to purchase a few things. mirrors are one of them. How is the installation over the raised bump for the stock vw mirrors, I dont want to drill up the door for mounting holes if these mirrors arent very good. Hows the build quality. Know of any places to get some good mirrors from,

Thanks
