On my 5 speed TR8, that single bolt that goes through the center of the gearbox mount, passes through the mount, then through a spacer and then bolts directly into the hole in the gearbox that is between where you have the two existing Rover SD1 rubber mounts.
With respect to the peg that bolts into the selector shaft. I beleive the peg should just slide fit inside the steel ball, the ball should stay in the nylon socket in the selector housing. If that's come out together then you will need to check the nylon cups that retain the ball (comapre it to the other one that is at the gear lever end. They should operate the same way)
Must be hard getting all the parts for a V8 installation Chris, good luck.
