the stock one just has two metal strips that bend in on either side, just take a small screwdriver or crevase tool and pull them out. as for the trd part, it's a sticker, you just need to peel it from the button it came on and stick it to your steering wheel.
omg, awesome avatar!!
lmao, after my one friend and i would get a kill, we would either
1. hump the dead body like your avatar
2. slap them then throw a sticky grenade on them
it's so fun cause it pisses people off
or you do all three!!
