Damn,sorry I missed this post..been off the forum for a while ,working a lot.
I sourced all the stuff from TCB auto parts in England.(see attached pic)
They are awesome to deal with.
A full rebuild like mine will cost you about $2.5K including parts and labour.
Let me know if I can help with more info.

It's all good, thanks anyway. I've since had some coilovers installed my my local mechanic, which in the process uncovered a lot of worn out and dodgy stuff under there which is now hopefully all sorted. Now my new mechanic is on to fixing the mess my old mechanic made of the entire electrical/ECU/sensor setup.

Hey FB, just curious, given their in the UK, did you liaise via email and get it shipped? Or what was the process. Again, lovely car

Hey mate...yup Paul from TCB is awesome.
Their service is impeccable.
Everything arrived in perfect condition and as advertised.
He went to ALOT of trouble on my behalf..great guy...5 stars.
ps. he has a wicked Celica GT4 with our engine in it making good HP.
Ask him for a pic...I recommend you telephone him after initial email contact as a few minutes on the phone works wonders.

Great, thanks mate
