I can guarantee QJB122 will fit. I've used them myself, that's how I know the part number :wink:
They come in at around 8 quid each on eBay
To be honest though, from experience these new 'rubber' gaiters only last a couple of years before they need replacing again.
Whatever material they use is nowhere near as good as the OEM stuff. I had a spare one on the shelf and even without use it had started to perish!
I got sick of doing the job so invested some time in finding an alternative.
Look for
Neoprene Extra Stretchy Universal Fit CV Boots the material is far superior, much more flexible and less prone to splitting.
They are designed to be fitted using a special fitting cone without the need to remove the CV joint, but you don't have to buy a fitting tool and can still use them like a standard boot. You have to cut them to size, but it's easy to do.
I've had a set on my D for a good few years now and they are holding up much better then the other type.
