If its just those generic u-clamp-style bushes check out autobahn or any suspension shop. I got some from a suspension guy and they were dirt cheap. They're yellow poly things. I even used them when I had a custom front sway bar bent up to the same shape as the standard mk1 gti one and used the original vw brackets, I just had to cut the poly bushes to the right shape which is pretty easy with that material.
