You cannot keep the vacuum brake booster or your power steering pump. You’ll need hydroboost for the brakes and a 96-04 power steering pump. Or Volvo electric power steering pump. Or manual brakes and steering
That’s not a bad idea. I’ve got an 07 and love it.probably gonna go buy this 06 mustang with a few goodies already on it for $6500
