Thanks for everyone advice on this. I'm proud to say nothing got broken
some pics:
I started with the seatbelts on the columns.

Made my way around.
The most fragile clips are definitely on the rear. None were broken.
A bit tricky coming out. I laid the seats back all the way to make way.
Couple of the corners cracked off so I taped them up along with any other cracks. Very fragile.
Cleaned up the old foam backing with a wire brush and used compressed air to blow off the loosened materials.
Laid out the fabric like SuperRA said and put everything back in. Total time took about 2 hrs once all the supplies are acquired.

I'm loving it

...hope it ages well. What do you think?
