Hi, George sorry to be the bearer of bad news but what you describe above is totally wrong and will not result in a safe and proper modification and also the handling of the car will be adversely affected.
Why I hear you say
1 the threads on the track rods on the sierra rack are 14x2
2 you cannot simply cut down the rods and rethread they are rolled threads,
rolling a thread increases the od of the thread cutting with a die does not
3 the rack length is totaly wrong it needs the inner ball joints to line up with a theoretical line drawn between the wishbone pivots when the steering is in a dead ahead position (there is a pic of this in the book)
if you dont have the correct rack length you car will suffer from acute bump steer and be very dangerous
I hope you understand what ive written and take it onboard for your own safety
Ray
