BMWCCA beat me to it. That's what I would be looking for.
Though, to be fair, the aftermarket kits are MUCH better now. It's to the point where it's limited only by the skill level of the person assembling the available parts... there are parts that EXACTLY match the originals, available in the aftermarket, now. I know, as I've BUILT a number of them...
