[G1947]

G'day All
I need some help from the experts here, please.
I was originally going to use the Drum braked LX Torana rear end that came out of the donor car.
Now that I have to use an LS1, I am thinking maybe I should go up a bit in strength and to four wheel discs.
The VN/P/R Commodore is readily available. Does anyone have comparable width measurements of the Commodore and Torana? (Say outside of Drum/Drum to outside Disc/Disc, IE Wheel Mounting faces?)
Will the Commodore fit the early DRB? Mine has the rear cross member notched for a 9", so I assume it will fit that way.
And do the mounting points on the Commodore rear need to be moved if it will?
And, if I use the Commodore rear, what front discs will fit the Torana Stub axles to keep the stud pattern the same. Will VT fit?
And, if I change both ends, can I still use the Torana Master Cylinder?

Thanks
Garry
