question?
i know there is a ton out there for a 2gdfis w/ tt but my buddy has an fc and a buch of parts i was wondering if i was able to get one of his extra dizzys and a set of his extra coils is there a way i can set it up to do basicly the same thing or should i just go to the 2gdfis w/ tt and if i have to do that do i use the trailing or leading coils from the fc? thanks guys

The 2nd gen uses what is called a Crank Angle Sensor (CAS) in the place of the distributor. You can't use the CAS directly with the coils. You would need an ECU to convert the signal and control the advance. It would be possible to use the CAS, coils, and the 2nd gen ECU. It would require quite a bit of wiring and adding sensors to make it work. Probably not worth it, although it would make it easier to add fuel injection to your 12A or to do a FI 13b swap later.
The TT setup is used to convert the signal from the 1st gen distributor to work with the 2nd gen leading coil. The advance is controlled by the distributor, so an ECU is not needed. There isn't a good way to use the 2nd gen trailing coils yet unless you have an ECU that is designed to work with rotary ignition. Typically, people just leave the trailing stock, as its contribution is very small anyway. There is nothing to really be gained by upgrading the trailing.
Another option is the regular 2GCDFIS. Real easy to install. You only need the 2nd gen leading coil. It is then setup to be fired by the 1st gen ignitor. You can do this mod without removing the 2nd gen ignitor (many write-ups tell you to remove the ignitor). If you keep the ignitor in place, you can do the TT or ECU fired ignition later.
