Rear Pillar Speaker Size

Hi i'm attempting to replace the stereo in my 2003 Yukon and i was just wondering if anybody on here knew the exact size of the rear pillar speakers. Thanks

Going by all my research online I believe they are 3.5 inch. I cant find the mounting depth though

They are a nonstandard size and I believe they are glued into the plastic. You'll have to make something fit if you want to even mess with them. Just pull the pillars off and have a look, it takes minutes.

I have a set of pioneer 3.5 coax and the definitely won't fit there. Maybe a 3" or 2.5"
