Identification, need a little help Options

[1bwilson]

So I drove to the mall today and when I slowed doen I could hear this knocking and rattling of metal. After a little bit of investigating I found out that a lug nut just up and broke off of my driver side rear rotor. What exactly do I need?Ive never had the need to take anything off back there so Im not really that farmilar with the suspension. Is it the rotor, hub...... Also will it swap with a 5th gen celica gts? Thanks guys

Thanks for all the help. I'll take a look at it today.

My header is "Custom". Ive tried tracking it back to who made it (I got it off e-bay years ago). As far as Ive found out its the header that was used on one of the burien cars before thay came out with a turbo kit. Not sure if its true or not. Its pretty old now though but still works.

All the TBA stuff in my profile has been there for a good while. Ive spent yeras preping my car for a turbo and am finally getting around to installing it.

Ive got CP pistons, 3sgte rods P&Ped head w/ valve job, head studs, metal head gasket........... ect. It should be pretty nice once its all done.
