Ok it seems my one needs replacing.. . but after reading around it appears theres many different types.. and now I'm just ocnfused

and with my net failing ive just given up searching and figured id ask.

I need help identifying in which i need to get. perhaps a partnumber aswell could help?

I have a 4AGE 16V with a t50.

I have a forsales ad in the NSW section if theres any other info needed of I.D


Thanks alot.

edit: i've just called around just saying i got a 4age rwd. and i found place in stock. I've been quoted 95 plus trade in of my shonky one. i feel like I'm being ripped a little.. Do these go cheaper? although this one is reco'ed...
