    For application for a 1969-70 Mustang firewall main harness grommet, this grommet is a bit too small in diameter. The Mustang’s firewall hole opening is 1-1/2” in diameter, while this is for a 1-1/16” hole. Other than that, this would be a perfect replica replacement for the original factory grommet.
