Okay so i have the tanabe concept g, but DIDNT know that they take the stock bolts and already have groves for the bolt's threads. I lost the nuts for the spring bolts somewhere, so if anyone knows where i can get them that wold be great. right now i have a 5/16 bolt and nut on there, but i think i want the OEM ones better. Thanks.

 

Toyota might be able to provide you with OEM for a price. but other than that hardware store is another choice.

 

i got some layin around the house, you need two right?? pm me

 

There you go.

 

you can get em from the dealer... ive broken alot of those bolts haha. they are about 12 bucks for the bolt inluding the spring. and u need two... so yea...
