V8 Swap
Since you have the donor here is what I would do:
The most important thing is to get some system to keep your parts and bolts segregated. I would get plastic "baggies" and keep the bolts in baggies and label them. Also I would mark SAE Thread or Metric thread and the size wrench that fits them. I just went thru what you are about to do. There will be many things on the donor car that will be a standard thread and will be metric on the later model. There is no rhyme or reason what is SAE and and what is metric. I experienced this on removing a motor and transmission from an 88GT and putting it in a 92 GT. Get a digital camera and take pictures for future reference. Believe me the length of time it takes to do this you will not remember what bolts go where.
I would switch out components one for one as much as I could. I would re move the rear end from the GT and put it in the other car before I would take on another part of the car.
I would remove engine and transmission together. I would change out the entire front end as a unit. (K-frame,shocks,upper and lower control arms,spindles and brake rotors)
Small things you will need to change out is the master cylinder and power booster, pedal assembly, computer and engine wiring assembly.
I would not get rid of the donor car until everything was completed and working on the new car. I think every thing on the old car will work on the later model.
