Easy questions for a seasoned Burb owner...(GMC)

[Aarons72]

I am a new burb owner, so I am trying to figure all this out, but finding GMC info can be fairly tough...anyway, Im guessing most of you guys can just give the answers the easy way so I can get on with my life...here are some questions.

1. Are there reproduction tailgate emblems? And what does this tailgate emblem look like? (1971)

2. Is there reproduction molding kits for suburbans or do I need to find original stuff? The stuff just under the glass all the way around and the lower fatty moldings.

3. Do pickup truck side marker lights fit suburbans?

4. If I tear out all my factory air unit (starts in the back and runs the entire roof of the burb) am I going to face any issues that I would not expect to encounter?

Thanks guys!
