UNDERBODY ALIGNMENT
"F" Body Styles
DESCRIPTION
"F" series bodies are of unitized construction. A
stub frame supports the front end sheet metal,
front suspension, engine and other mechanical com-
ponents. Unitized construction demands that under-
body components be properly aligned to insure
correct suspension location. In the event of col-
lision damage it is important that the underbody be
thoroughly checked and, if necessary, realigned in
order to accurately establish suspension locations.
The tools and materials needed to check alignment
and
repair collision damage are described in
the Corvair and Chevy II Underbody Alignment
sections.
To assist in checking alignment of the underbody
components, repairing minor underbody damage or
locating replacement parts, the following under-
body dimensions and alignment checking informa-
tion is presented.
UNDERBODY ALIGNMENT REFERENCE
POINT DIMENSIONS (Fig. 3-14)
Dimensions to gage holes are measured to dead
center of the holes and flush to adjacent surface
metal unless otherwise specified.
The
master
gage holes adjacent to the #1 body mount and in
the side rails near the rear spring front attach-
ment,
are
key locations
and should be used
wherever possible as a basis for checking other
reference points.
