Dart Rear Extensions

Gasket is stiff plastic approx. 0.032" thick
they do not cover to the outer edge of extension
there is oem paint on outer edge of gasket (hard to get pic)

probably used to keep extension away from body to drain moisture
only found on one 71 dart both extensions
all extensions have 3 holes for trim screws not shown in pic

I plan to use plastic shim stock to fabricate mine
avail industrial supply house

oops not shown on left gasket extends 3/4 " past C/L of lower mtg stud (by keys d hook) to end of mounting lip sorry

Hope this helps
Thanks FABO
