I purchased a billet grill. It came with four pop-rivets. I removed me ugly stock grill.
The trouble I am having is the pop-riveter's head does not fit between the bars on the grill. How did everyone else install theirs?

 

Ok I have never seen this but I'm gonna take a guess
I guess you would take the plastic grille off you car and drill some holes in it then pop rivet the billet grill from behind you might try and look for some pre drilled holes in the billet grille

 

Wrong, the billet grill has specific holes to use the rivets in. I would drill the hole and rivet it from the front, but the attachment on the back of the billet grill (for the pop-rivet) hold both bars above and below it together. So I can't just bend them apart.

 

Do the instructions say rivet it from the front?

If you can't fit it from the front I would have to say go from behind like this

billetgrille|Plasticgrille|rivetshooting this way <---

that or get a rivet gun with a extended barrel or whatever it's called

 

Alright, I give, screws with butterflys. Worked fine.

 

i guess i must have got the ghetto version of the grill. mine came with 4 black tie wraps.lol i thought it was crazy at first but it all looked good and stayed on well until i hit racoon.lol. don't ask long story. but if ur up for going that way it didnt take but maybe 20min. and no holes would be left permanately. just my worthless .02. Later

 

It's not ghetto at all actually I like the zip tie version alot better my friends only took like 5 mins to get put on and ready to go

 

Won't the zip ties wear out after some time and weather?

 

Zip tie's last for about 5 years out in the weather I use them to tie cable to the bases of sat. dishes and they last pretty damned long
