Sigma 150-500mm f5-6.3 Canon fit missing micro "Housing" Screws ? (1 Viewer)

Was just trying to fit Sigma to my 7D and soon noticed that a couple of the lens housing/Lens Mount screws had disappeared.
Last time I used it in March I never noticed that they were missing, when I put it away.
Does anyone know where I can get hold of these screws?

i.e." the lens mount ring" which lines up a small dot on both the camera body and the lens
Your help greatly appreciated.

Your best bet would be to pop in to lehmans repair centre in Stoke on Trent ,they should have some there and someone to fit them

Thanks but now sorted.
A bit of a rip off considering their size and the fact that they must have 1000's, but £6 inc postage, for four replacement screws from Sigma.
Arrived and fitted yesterday.
Amazing that these little objects are responsible for attaching the lens to the camera.
