Never been a 6-speed fan. The Tremec Magnum T-56's are much bigger, longer, heavier, and more expensive....and you really don't get into a situation where you ever need a 6th gear. Most of the engines for Cobras are a little fussier than most and just don't like to be pulled down to 1200-1300 rpm.

The most common combination for a BBF is a Quicktime bellhousing, McLeod/RAM clutch kit, a TKO 600, and a hydraulic slave setup. Pretty inexpensive in the scheme of things and pretty bulletproof.
