Hmm the dimensions are:
A= width 113cm (44.5")
B=height 35cm (13.75")
C=hole 10x10cm (4x4")
C=distance from edge to hole 28cm (11")
Sounds like it could be the genuine part, any chance of a photo of it installed so I can see how brackets attach?
Looks like Ive failed the Renault Crypton Fatcor then..
