I searched and I have the fluffy pdf thing; couldn't find it. Sorry to those who think I could have done better, and thank you to those who may answer my question.

What size bolts are used with the OEM trunk spoiler?

Yah, not the most interesting topic lol.

I'll man up and trialanderror it.

umm, i'd look but i don't even know where i put them. most people who have the oem spoiler don't take it off to see what bolt size it is, or even if they do take it off, like me, wouldn't know what size it is :( sorry man! maybe you can buy like a multi-size pack and find the size that way.

M6x1.00 x 20mm lg... I do believe.... I'll have to see if I have them in the garage...

Zoomnrx8, tight, thanks. I really should have put them in a baggie with a label on 'em. But yah, I was thinking like a m5 or m6. I'll try out your specs.
