So thought i had better get it installed, Had to bend the arm a little to get it away from the fuel pipes but other than that it all went together fine.
Seems a bit stiff getting out of park, not sure if thats down to the push button system, the angle the rods at,,a 4L60e thing or its simply just because i am not sat down and have nothing to lever against.
Will worry about that later, same with the D300 shifter which i suspect is bent way too far back and will need warming up and tweaking at some point.
