No I didn't,
I replaced the front drive shaft with the Ext shaft from Cobra Transmissions.
I was concerned about the extra tension on the joint with the two discs.
The guys a Cobra were amazing and it was delivered to Australia within 3 days with the DHL $77 option. It was a little hard to install being that it's longer. It misses by about 2mm, but a little stretching of the engine/gearbox mounts and pop in it goes.
Would love to hear how you go if you try the dual discs.
