How to Shorten a VW Pan

The
thin sheet metal floor can now be welded; however, a dart must be
cut out of the rear corner before the outside edges of the pan will
come together. Draw a line from the rear outside corners of the
rear pan sections down along the inside radius of the corner to
the bottom of the floor pan. Then extend the line straight and parallel
to the outside edge forward to the cut between the halves. Use the
sawsall to cut along this line so that the rear corner is loose
but not cut all the way off. Now fold the loose corner in until
the outside edges of the pan match. Use the silver pencil to draw
a line on the overlapped portion of the rear section. Pull out the
loose corner and cut off the excess material at the marked line
with tin shears. Now fold the loose corner back in place; clamp
it; and weld it.
To strengthen the tunnel weld, cut one 1-1/2 inch wide strip from
the removed tunnel piece and weld it over the top of the tunnel
weld. If the pan has slots next to the emergency hand brake for
heater controls, these slots must be welded shut and strengthened.
Cut the remaining piece of the tunnel lengthwise into 1-1/2 inch
wide strips. Weld one strip on each side of the tunnel on the vertical
surface just below the hand brake opening. The cut narrow strips
and weld them over the heater slots and to the upper edge of the
straps that were just welded into place.
The
last detail is to shorten the clutch, accelerator, and fuel lines
that are sticking out the rear of the chassis. Use the measurements
for correct length that were made before the chassis was cut in
half.
Re-install the fuel line grommet to keep it from rattling and braze
the clutch and accelerator cables tubes to the edge of the pan just
under the rear access cover. Don't forget that the shift rod must
also be shortened 14-1/4 inches. When you shorten the rod, scribe
a horizontal line on the rod before you cut it to be sure that the
two halves go back together without any twist. Install a new nylon
shift rod bushing inside the tunnel just behind the shifter opening
before putting the shift rod back in place.
I find
that cleaning the pan before painting is best accomplished with
a heavy duty wire cup brush on a welding grinder (sand blasting
is optimum). After a good coat of rubberized undercoating on the
bottom and rust inhibitor paint to the top you are now ready to
Rock and Roll (roll over rocks) !
