Just completely removed my seats to thoroughly clean and renovated them.
I noticed these four plastic clips of the shelf behind them. They look like something can clip into them. What are they?
Hold net upside down, rod up/elastic down.
Put hooks at ends of elastic into holes in quarter panels.
Rotate until rod along net is in line with slots on bulkhead.
Tap rod into each slot with rubber*mallet/hammer.
*I didn't have one, so used a 2lb hammer ... carefully.
