I apologise as I didn't take a ton of pictures but this is pretty straight forward. I have also included the video that I watched to learn how to do this.

Needed:
Flat Head Screwdriver (preferably a longer one)
17mm Socket

Time: 30 minutes per side

Difficulty: 2/10

1. Disconnect battery
2. Move seats all the way forward and up to get easy access to the seat attached connection.
3. Remove seatbelt connection cover and use screwdriver to remove the seatbelt from the seat. There is a tab that you need to pry out and push down to remove.
4. Carefully place screwdriver under the upper B pillar near the edge and carefully pry it out. There are two metal clips holding it in place at the bottom.
5. Gently pull back the top of the lower B pillar back. You can then gently pry up the rear of the lower B pillar. The front of it you need to lift the door trim before you can release the B pillar.
6. At this point the upper B pillar is held in place at the top and the lower B pillar is freed.
7. Pass the seat attached piece through the upper B pillar trim.
8. Remove the upper seat belt connection with the 17mm socket.
9. Remove the lower seat belt connection with 17mm socket.
10. Carefully remove the seat belt housing and unplug the airbag sensor. The yellow clip needs to come out (I used a knife, a small screwdriver tip should do it as well). Once the clip is out, slowly remove the purple plug as to not damage.
11. Seatbelt should know be free.
12. Re-install in reverse order.


Things to note:
1. Seatbelt won't come out unless the housing is in the installed 90° angle position.
2. The hardest part for me was reinstalling the lower B pillar trim at the top. I included a picture of this below.
3. When re-installing the upper B pillar. Make sure to line up the seat belt adjustment on the trim and the mechanism.

Upper portion of lower B pillar trim. You want to line up the green circle part of the clip just above the blue circles and push them in. This takes a little bit of time as to get this right.

Where to purchase?
I purchased these from Safety Restore in Westfield, MA. Super fast turnaround and tons of options. These go for $75 per belt plus shipping but you can often find 25% off coupons (like "GOONZSQUAD" as of 3/21/19). Basically you send in your belts, they remove the black and reinstall the color of your choice. You are either without seatbelts for a week or you can buy a used set to send in (as I did).
