Well, here is my findings, on the air shock installation.

The only modification, needed to use the air shock, is a longer top
mounting bolt, to accomidate spacers on the inside of the shock, to
clear the wheel well.

Mind you, I installed them on my Type- 2, but the application is the
same.

The stock shock bolt is 4" long on the top, so I added 2" inch longer
bolt, with 4, 12mm washers to the inside of the shock mount so it would
clear the wheel well.

Pretty simple.

The shocks I installed are for an 86 syncro, Gabriel part number 39215.

Will work well on a sagging butted Vanagon.

Did work well on Clementie for about 20 minutes.

The type -2's have torsion bars, and she was sagging pretty good, in her
butt.

When I leveled her out with the air shocks, it must have cranked the
torsion bars back to where they should be a little too much, and after
hitting one of Illinois finer pot holes on the expressay, I think I
fractuered a torsion bar.

A lot of banging coming from the right rear wheel area after hyper
extending the suspension when going through dips, wallows, bumps.

I will prevail on this minor set-back.!!

But like I said, the air shocks will work well, on the Vanagon rear
suspension with the coil springs.
