Front valance fitment

I was trying to install a MSA replica BRE front lip (vented) and noticed that there is gap between the end of the spoiler and the bottom of the front radiator support. I think this might be how the replica molds are made, and I'm not sure.

Based on this video it appears that an front spoiler from BRE will just about touch the lower radiator support.

My early 260z  was missing the lower valance from the car, I had acquired one for a 240z from a member on HybridZ and modified the mounting points to fit my 260z. I think its highly likely that I messed up the fitment of the valance on the car, is there supposed to be a gap between the valance and the lower radiator support to begin with?

I just want to know if the issue is with my valance fitment, or a molding issue with the MSA BRE lips.

If you have a BRE lip and can share a picture that would be great! ?
