If Getrag with 1:1 5th gear, then the original diff ratio is good. The manual trans will be shorter, requiring a longer drive shaft.

Single mass flywheels work with single mass transmissions, dual mass flywheels work with dual mass transmissions. The Getrag 5 speeds came in both flavors.

The 717.404 is single mass, 717.450 is dual mass
