Yeah, sorry, I meant search on the hidplanet.com forum.
The main thing would be to get a lens which would still fit in the stock headlight housing. And for the brakets, I'm not too sure mate. Best to do some research on the hidplanet.com forum. See what others are doing and apply your knowledge.
I think there should also be a write up on how to retrofit hids into the r32 headlight. I'll try and find the thread for you. It's on sau somewhere.
