OEM spare tire install

Ok, so I went through and measured the original foam.

The two "rear" pieces (nearest the trunk opening) are 6cm square by 3cm thick. The two "front" pieces are 5cm square by 2cm thick.

The two rear (larger) pieces are placed at 46-52cm and 28-34cm from the near side, and 22-28cm from the seam. The two (small) pieces line up with the outer edges (52cm and 28cm from the near side) and are 4-9cm from the seam

This all will make more sense if you look at the pictures.

I cut some chunks of about the right size from the original foam blocks, and wrapped them in duct tape because they were really messy. I stuck them on with rolled-up tape; once the tire and wheel are in, the compression will keep them in place.

 

I used filet knife, and the cutting was very neat. Thanks for sharing, please post pictures when you are done.

 

Looking at that photo, and looking back at @Hammersmith 's posts on the first couple of pages, bemoaning the waste of money on the order, I think the part number for that deck board should have been a clue - "58410-47040-C1". That's not a proper part number is it? That's just the same part with some bits stuck on.
