So was trying to change my pads today and while trying to take out the bridge bolt, the head snapped off. I was able to get the thread part out of the bolt out but now I need the part number.

I searched a web archive of Sewell's part diagrams but could only come up with Stock Code: 049470W010. Can anybody confirm if this part number contains the bolt that I'm looking for? I think this kit only has the metal shim and the 2 pins. If somebody's got the exact number that'd be fantastic.

Greatly appreciated if anybody can help me out. Thanks a lot in advance.

Here's the part diagram I was talking about:

 

Crossed it on lexussouthatlantaparts.com and you are correct, I order from them. $25 for the kit
