I am currently trying to locate a pair of inner tie rod ends for my 2003 Vectra CDXi (GSI in UK) 3.2 V6 with 17" rims. I have found a number on eBay which apparently aren't suitable for the 17" rims or sports suspension. What are the differences between the different types?

I also have limitations living in Australia as many European outlets won't post here. I have found a seller that says the part will work but I want to be sure. Any ideas?
