Blazing 72 your part numbers match up with what my dealer is telling me for the clutch kit. I had them order the Boss 302 clutch kit just in case I decide to go that route and in case the Centerforce clutch does not make it here in time on Monday.

I confirmed the slave cylinder for the 2013 Boss 302 and the 2013 GT are the same BR3Z*7A508*B and ordered one of those.

The 2013 Boss 302 flywheel is CR3Z*6375*A
The 2013 GT flywheel is BR3Z*6375*D
As you say the Boss 302 Clutch kit works on 2013 GT flywheel using 9 bolts instead of 6. The bolts for Boss and GT have same part no. BR3Z-6379*A. Not sure if one time use, but going to change out the bolts since only $1.00 each. If I use Centerforce dual friction clutch supposedly only attach with 6 bolts and + 3 pins. Thus apparently with Boss Flywheel use 6 bolts and 3 step down pins and with GT use 6 bolts and 3 straight side pins. I ordered both flywheels to make sure I have the proper parts.

Does anyone see a balancing or any other issue with using a Boss 302 flywheel on a GT mustang?
