C2-body checking dimensions

[tony reilly]

The 1964 assembly manual has several pages (C3.00,C5.00, etc) with about 100 3D body points. Does anyone know if more extensive data (like a couple of thousand)of these point data is available?

Re: C2-body checking dimensions

We had a huge illustrated "Body Checking Manual" in the plant with about 800 x-y-z points for checking bodies on the layout surface plate (long before the days of digitizers and computer-driven CMM machines), but it was strictly an internal document and was never published outside of GM. All the points were referenced to the GM Master Body Design Grid System, which doesn't mean much on a finished car; it took over an hour just to set up the bare body position on the plate to the design "0" grid lines with riser blocks and shims before we could start checking points to design.
