It does look hectic doesn't it! Honestly, it is not I just have a way with making things overly detailed.
The total cost was about 70 dollars. Maybe 38 and some change for the red fabric.
To break it down barney style:
Remove current seat-belts
Separate belts from spindles
Bring new fabric and old belts and hardware to shoe store to get changed over.
Put new belts in spindles
Install back into car.
I should have just made it one post and those 5 lines.
