sion parts changed. CriticaTstructural areas were magnafluxed and repaired or re
placed. A spoiler was built and installed and miscellaneous sheet metal changes made
in preparation for tests.
The test results with windows out indicated excellent handling and speed \
capability almost equal to theT5odge assuming no engine performance degradation j
between installations. /
Following the Talladega test the Plymouth began preparation for tests
cheduled at Darlington on 20 - 25 April.
A factory representative from Hooker headers arrived and began build up
of a new header system with larger branches and interchangeable length interconnect
pieces to accommodate track testing with varying length sections. This build up re
