hello everyone just looking for info on convertible specific defoggers, purchased n.o.s. one a couple weeks ago but the installation details leave alot to be desired. anybody have pics of one installed? mine is going on the 69 project i'm currently engaged in. or if someone else might have a diagram of installation maybe i could purchase a copy of it. also is there a spacer ring that mounts to the fan/motor housing that in turn mounts to the divider/ rear seat upright? thanks in advance for all help. michael
