Yes, Astra VX line is pre facelift, can't say 100% whether they are exactly the same fit but there is a few visual difference that I can see, one is the badge and trim that the badge sits on. The badge on the facelift sits at the bottom of the grill, whereas on the vx line the bages sits at the top of the grill. From looking at a few images on google for the facelift bumper it looks as though there's a small semi-circle notch cut out of the bumper where the badge sits, and at the bottom of the bumper it is moulded to look like it sticks out a bit, a bit more agressive look.
You may be able to get away with just replacing the vx line top grill and trim with a facelift badge and trim?
