Changed headlight units, 2 screws left over... should i worry?

So, i figure i would make the title a bit humorous sounding, but still true. I changed my headlight units after a sea bird decided he wanted to go through one of them....

Everything installed fine, but i just could not get the angle on the last screws under the fender back on. Getting them on was bad enough, but getting them back in felt impossible. When as is said and done, everything still feels rock solid; the headlights dont budge, and the body panels still feel tight.

Aside from providing one more securing point on teh headlight, am i going to run into problems if i font get these suckers back in (oh, and there is a rainstorm rolling in, so i really wouldn't be able to get to it tonight... sigh)..

 

I have been looking at the BHLM threads and some never put those screws back in for that reason and don't have any problems.
