Not sure what to do here...

I have a 96 gmc fullsize that I am bagging the front of. Everything has been going pretty smooth considering i have never done this and i have done everything by myself. Just one lil question left, do I have to drill a hole in my coil spring perch for my airline to go to my bag? I mean I'm pretty sur ei have to, I see no way around it. Just thought maybe someone out there had a pic of this. I hope someone helps me out because I plan on hearing the front hit the ground tonight sometime. Thanks in advance.
