Pretty much just repeating the 2-6 steps for the left side. Riveting the ribs to the floors and also riveted in the plastic buffers to the floor. The instructions say you can wait til after you paint but see no reason to paint the top of the baggage floor. On the RV-7A I had a nice piece of upholstery from Flightline Interiors and if one isn't available for the RV-12, I'll just make one.
One problem is the smallVan's recommended manual pop riveter has crapped out, apparently for good. It just won't pull anything. I had the problem when I first bought it and I talked to ATS aboout replacing it but then it started working and I figured "screw it."
