Today I installed my first GT engine by myself in 2.5 hr.
Here are the steps i followed. They may not be the best but they worked !
This is what supported the engine for over 3 weeks.

This is how i got it in position. Just take it easy.
R engine mount on the car
Center engine mount and O2 sensor on the engine.
L engine mount on the floor.

with this attached

Put bolts in 1/2 way until all are in.
Fastner sequence:
1. one bolt in R engine mount
2. L mount center bolt
3. 3 bolts in L holder
4. 3 bolts into trans
5. trans bottom brace
[put jack under engine and remove crane]
6. Center mt, top bolt
7. Center mt, bottom bolt
8. connect shifter and brace
9. 2 exhaust bolts
10. 2nd bolt in R mount
Here it is in.
