Replacing Dart Tail-Light Sockets????
The sheet metal of the socket is rolled around the potmetal housing. Once it is ripped out of there a different socket can be installed. Either the snapped in type or the later model twist to lock in type with a little more work at the fixture hole. My 67 fish has huge rear fixtures with only one little 1157 in each. The red lense gets darker too. I have added 2 more bulb sockets to each fixture on 2 different cars so far.
