Hey guys, Andy again. I am completely clueless here, so please help us out! I had a crash a few weeks back (3rd day on my Ps, yikes), and ended up in a ditch. After some panelbeating, I took it back on the road and it handled terribly, the steering (still) veers slightly to the left when I take my hands off the wheel, and if the steering wheel is centred, the car veers to the right. I took the thing to get a 4-wheel realignment, but the man said there's no point, because something is out of whack. I CANNOT RECALL what this was! He said the car would need some new parts (something was bent in the rear) before an realignment would work, and the parts cost about $110 and $130, including labour... can anyone think of what these could be, as I'm going to take it down there to get it fixed, but I have no idea what the parts are called! Any ideas? Thanks in advance!

G'day gents, Andy from Victoria here, recently bought an '89 R31 Ti. Runs great and everything, great on the outside, but the interior is bordering on disgraceful. There are quite a few cosmetic and maintenance things I'd like to get done for it. - Caps missing for power window switches on the driver side - Broken sunroof seals!! (this one is urgent, the sunroof is ASC) - Caps for door locks are loose/missing - Roof light switch is broken (I'm told a ball bearing is missing?) - New dashboard lightglobes (current ones are so weak it's not funny) - There's a STOP TAIL light in the middle lights display that lights up whenever I brake while the low-power lights are switched on or whenever I accelerate really hard, is this normal, or a wiring problem by a mechanic? - There's a creaking/clicking noise everytime I turn the steering wheel slightly to the left (this isn't the several loud clicks you get when you turn the wheel 360 degrees, it's a quieter, more annoying version of that) I have absolutely no clue about cars or repairs (this is my first), does anybody know any Nissan/Skyline specialists in the eastern area who can do this? Thanks in advance!
