When I was camping at
Cibbets Flats last month, Gina pointed out some abandoned lumber, that someone wanted to burn, but campfires were restricted that weekend. I found 4 identical pieces, 2" x 2 3/4" x 23" long.
Then I studied the floor anchors in the van. They are made out of rods with different diameters. This is so you do not install them in the wrong positions; preserving proper seat belt function. I discovered:
The rear anchor rods on both seats are the same. 3/8" diameter.
The forward anchor rods on the
Passenger side seat are 1/2" diameter.
The forward anchor rods on the
Driver's side seat are 1/4" diameter.
The forward-to-rear rod spacing on the
Passenger side seat is 11 3/8" centerline-to-centerline.
The forward-to-rear rod spacing on the
Driver's side seat is 11 5/8" centerline-to-centerline.
I went to
Home Depot and bought galvanized steel rods:
2 each at 3/8" diameter
1 each at 1/2" diameter
1 each at 1/4" diameter
They are sold in 36" lengths. I cut them down to 23".
Then I drilled appropriate sized holes, 1 inch deep, at appropriate spacing that was different for each pair of wood blocks.
This got me 4 blocks and 4 rods:
