General LSX Automobile Discussion - What bolt size for Lower air box assembly?

Hey guys, kind of a strange question i know lol. When I bought my car I had the KN FIPK system, but I wanted to go back to stock setup. I bought a used WS6 lower air box, but I need to know what size bolts and washers it takes to secure it? Anybody know off hand? Thanks for all your help!

i think is mainly pushpins iirc. if not, a metric bolt with a 10mm hex head would probably be it. are you selling the car or something?

No i'm not selling, I actually bought it about a month ago with the KN FIPK intake and want to go to the lid setup. I bought a used WS6 lower air box, but it didn't come with the bolts to mount it. Funny thing is this is my third WS6 and I can't remember what mounted it. Thanks for your help, I'll check that size out!
