Tuet 1260 to LS!
You will need an input with the same 2.97 ratio ( Fcars are 2.66) A GTO input may work.
The rear mount and shifter location will not be correct.
There is no provision for the torque arm mount on the extension.
You will have to calibrate the speed output.
There is no skip shift connection.
It can be done with some effort. You might be better off trading it off & getting the right box.
