My B5.5 has a front end wobble which i posted previously and was advised it is possibly one of the bushes starting to go. The car has just rolled over the 200k mile so i might as well change both front suspension setups.
As this car is just a work horse i am just going to replace it with a cheap set from ebay. However, i'm unsure of which set to get as some offer 16mm bushings and others 20mm and some don't even state size

Which size do i need?
I am working away and don't have access to the car to check but want to order the parts up ready for me arriving home.
Any help would be appreciated.
