no, incorrect and AGAIN:
1999 & 2000 year Mustang GT's have Windsor Engines in them and IN 1999 & 2000 the Mustang GT's wth the Windsor engine have 8 bolt flywheel and 8 bolt crank.
1996 to 1998 Mustang GT's have Romeo engines in them and have 6 bolt flywheels and
2001 to 2004 Mustang GT's have Romeo engines in them and have 6 bolt flywheels and 6 bolt cranks and a 3650 trans.
ALL DOHC Cobras have 8 bolt flywheels and cranks wth all manual trans
2004 Mach 1's wth sticks have 8 bolt flywheels and cranks while the automatic Mach 1's have 6 bolt flywheels and cranks
NOTHING IN THE VIN TELLS YOU WHAT ENGINE PLANT THE ENGINE IS FROM, THATS BAD INFO.
I don't think I can make this ANY clearer
