This is the heavy duty crossmember directly behind the deformation panel. Correct for all bay windows with later 'square' bumpers 72-79.
This is a genuine VW part, but from the VW factory in Brazil, the contour shape of the inner face where it meets the chassis rails is slightly different to the German version, so you will need to do a small alteration to fit correctly, the outer chassis legs need to be shortened slightly until the middle 2 rails meet the face of the this panel.
For more info please give us a call. This is the same version sold by everyone else, they all need alteration, its just we prefer to tell you upfront! We have used them ourselves and they are fine once you know the difference and how to attack it.
