Daniel,
I am about 2/3 done with my GT and I posted several facts in this thread:

Be advised that the MK II cars were fibreglass panels, not aluminum. Only the roof (not doors) and A and B pillars were steel because they were part of the entire monocoque chassis structure. When constructed almost all cars had the chassis painted a medium blue. The body panels were painted all different for the '66 race.
There are many ways to detail the Trump kit better but if you're building a different car than the #2 (George Stauffer's restoration) you may need different fuel pumps, etc to replicate an exact car. If you want an accurate replica, you can't just slap other decals on as the cars all had detail differences. I chose to take license and build 'my' version as I would love to own it today but with period parts. I did that because you can't build an accurate #2 car even though that's what Trump is giving you.
The thread (which the OP never responded to!) may help you understand better.
Here is an excellent guide for metal finishes and arrangements as #1032 is being restored:
