FLOOR/FRAME CHECKPOINTS AND FRONT BODY SECnON GAUGES P 863 AND 863a
As already announced in the 1975 model information, checkpoints are welded to the floor/frame
assembly from 1975 models. The extent of damage is quickly diagnosed with the help of these
checkpoints and front body section gauge P 683 a (consisting of former gauge P 863 + additional
adaptor) .
The carrier pin of Type 930 Turbo is 21 mm higher. When measuring with front body section
gauge P 863,the distance between the upper edge of the gauge and the collar on the carrier pin
is 21 mm or, with the adaptor installed on the carrier pin, 13 rom.
The gauge can also be used to repair light front section damage (upsets up to 10 mm). Cars with
damage of this type no longer need to be installed on a straightening bench.
Installation of the gauge requires that the wheels, the guard, the carrier and the control arms be
removed. The gauge is then bolted to the front axle take-up points and front floor/frame checkpoints,
as illustrated above.
The distance from the rear floor/frame checkpoints and rear axle take-up points for the transmission
to the engine suspension is checked with a measuring staff.
This gauge is for checking only. It must be removed for straightening and welding operations
to prevent it from becoming bent through body distortions.

FLOOR/FRAME ASSEMBLY TYPE 930 TURBO
In comparison to the Type 911, the carrier pin <i the Type 930 Turbo is 21 mm higher. This has
caused changes to the floor/frame assembly in the area marked in white.
The border on the wheelhouse and floor plate is cut out about 70'mm higher than the control arm
to allow accessibility.
Note
If new wheel housings are required for repairs. make these openings in the borders on both sides and
weld the seams to the floor plate.
