I usually send a RAM flywheel along with a RAM clutch kit for my customers that have Roush engines.

You need a 157T flywheel (aluminum or steel), and the clutch will depend on the bellhousing you're using and how the slave cylinder is mounted.

If you have a factory style bell or a Quicktime bell currently, with the clutch fork pivoting on the passenger side, then a typical 10.5" diaphragm pressure plate with a late model Mustang throw out bearing is what you need.

With some insight into how your current setup is installed, I can provide part numbers that will work perfectly.
