I added the 2-port aluminum SVO MC to mine, but it also has the 73mm front calipers. Works great, but I have also heard of others staying with the stock MC/PV (in similar fashion to the '93 Cobra) and having that work fine as well.
I wrote a real nice tech article for another site that has lots of pictures and a parts list - if anyone is interested, I'd be happy to pass it along!
