Leaf my truck alone!

[External]

Hey guys, me again with another question.
So I ordered the guards from LMC, put it on, screwed and bolted it all back on only to have a huge gap between the cowl and the windshield.
I just removed it again to search the internet for instructions.
Came up empty so I searched here.
Looks like everyone seems to have no troubles.
I have the parts, it's off, I'd like to see this work.
Does anyone have any suggestions?
There was only one place with shims. Put them back in place.
The cowl didnt fit so well with the body lines in the first place. But it did not have that huge gap by the windshield. I'll try again. If it dont fit, I'll take pictures.
Thank you in advance for your thoughts.
