Rockwell Collins originally offered the following contour gaskets for mounting the ANT-60A on curved fuselages:
629-7897-001 32" inch radius
629-7897-002 47" inch radius
629-7897-003 62.5" inch radius
629-7897-004 38" inch radius
For flat fuselage installations, the original gasket (P/N 623-9614-001) supplied with the ANT-60A should be used.
Please note that availability of the contoured gaskets from Rockwell Collins may vary.
