new toy, lots of ???s- it's a HB

I just got an '87 HB, first Nissan. Now it's time to start playing with it.1. What do I need to do to put the newer front bumper on it, like the 95-7?2. What is involved in putting in the later model dash? Also, will the gauges work with this conversion without a lot of hassle?3. I may be wrong, but a LONG time ago, I seem to think I read an article about changing the rotors on one of these, and putting Toyota rotors on to change bolt pattern, did I dream this, or is it for real?

I'm sure I'll have 400 other questions, but this will get me started.thanksL8R
