Is there a kit thats specific for celicas the one in my 6th gen is a "universal" ebay kit, it fits but not the greatest the head unit doesnt sit very nice in the hole

You might've already figured this out by now, but you should just be able to use the radio brackets that came on your factory radio. My Pioneer double DIN unit had the proper holes for the factory brackets so it bolts up perfectly. I am not aware of a specific mounting kit for 6gc's apart from these factory brackets.

What kit are you using specifically, and what head unit? I'm curious to see this setup

i did get it figured out i found a set of factory brackets from a member for nothing except shipping cost and this is what i used to have
