VW Bus, How to Add a Rear Seatbelt
This is a mail I received from Uncle Joel. It is made including two faboluos ASCII drawings which I can not hide somewhere with no public access. To see the drawings your viewer have to be capable to select a fixed font character set.
ok, here goes. there are TWO sections, the first is about 100 lines. :)

that is, the dimensions of the hole are 71mm x 38mm (2-13/16in x
1-1/2in). but the front edge of the hole is 203mm (8in) below the top
edge of of the luggage area trim panel, while the rear edge of the hole
is 210 mm (8-1/4in) from that same edge. the hole is slightly tilted.
the notch is cut in the bottom to accomodate those three bolts that
hold the retractor assembly to the metal of the body.
also notice that this does NOT say anything about those 1986-1989
vanagons with air conditioning. the upper belt guide attachment point
will be behind the air conditioning housing that runs vertically over
the D-pillar. so you would have to cut a hold in the plastic a/c
housing to pass the belt through. (it helps to look at a 1990 or 1991
model, to see how the factory installation looks). in order to prevent
damage to the belt, the little plastic edging (that covers the edges
of the hole in the a/c housing) will have to be installed.

that is, the dimension of the bottom hole is 118mm x 102mm (4-5/8in x
4in). but the front edge of the hole is 216mm (8-1/2in) above the
bottom edge of the trim panel, while the rear edge of the hole is
245mm (9-5/8in) from that same edge. that is, the hole is slightly
tilted. the upper hole is 67mm x 38mm (2-5/8in x 1-1/2in) and appears
also to be slightly tilted. the upper hole has its bottom front edge
442mm (17-3/8in) from the bottom edge of the trim panel.
notice that the instructions do NOT say anything about those two 22mm
(7/8in) holes. both are 31mm (1-1/4in) from the closest edge of the trim
panel. the lower of the two is 203mm (8-1/8in) from the bottom edge,
while the upper of the two holes is 298mm (11-3/4in) above that same
bottom edge.
i have no idea what those holes are supposed to be used for.
