511 - 39T Gear Diff / Double Slipper

[djmcnz]

Hi there,

Is the correct combination for a 39T gear diff for a 511 with the upgrade kit:

54329 DB01 Gear Differential Unit
51463 TA06 Front Gear Differential

Or do I need something different/extra?

Additionally does the DB01 slipper + 501X adapted lay shaft fit in the 511 w/upgrade kit? It seems it should but it's pretty expensive to take a punt on.

Many thanks.
