Help On My 1987

[GMC85HighSierra]

Hi all, I've been working on my 1987 GMC Sierra, and I'm looking for thoughts on some things:

1. I am installing a Pioneer radio in my truck with Bluetooth and wireless calling. Where should I put the microphone for when I'm talking on the phone? My interior is a Sierra, so I don't have A-pillar trim or stuff like that.

2. How should I paint my truck? I want to paint it the stock colors, but I'm not sure how I want it painted. Not sure if I want to keep the dark blue down the center, or if I want to do the rockers down and the cab roof dark blue. I have the rear cab trim, so I'm kinda leaning towards the rockers and the cab (anyone have a pic/photoshop of that combo?). I also plan on getting it a tailgate band (if I can find one cheap enough). The truck is somewhat stock; trying to keep it looking mostly stock.

3. Will 31 BFGs fit under my truck? I'm running 235s right now, but l'm planning on getting new tires (trying to sell parts off another 87 GMC I parted out). My truck is stock height, and it's a 2WD 1/2 ton long box.

I included pics. I'm throwing bucket seats and a console in the truck. Bucket seats were a craigslist find; I drove an hour and a half to get them for $100. The console I restored to its former glory. Planning on doing my interior the dark gray color, but still have to get dash pad and door panels. Upgrading trim to Sierra Classic; have newish dash pad and gauge bezel in chrome, but not door panel trim yet. May add pillar trim and such, but I'll have to do some hunting to find it.

As I stated before, feel free to make suggestions. I'll need to know ASAP though, because I'm supposed to get it painted in a few weeks. Thanks
