The PAR46 decklights are appropriate for '82 - '92 models with '92 being the transition year for the later Federal Signal decklights. The blue PAR46 was introduced in 1984.
Just a minor nit on the bracket for the blue light -as it is shown here and in the restoration document it's not the same type that was commonly employed on the Mustangs. The more correct type is an "L" bracket that mounts entirely on the top of the package shelf and orients the connection end of the light toward the sailpanel rather than toward the center of the car:
In any case, the correct blue light bracket is quite simple and shouldn't be hard to have fabbed up.
The Micor and CCA/MPA2 setup is good for the '82-'88 models, with '88 being the transition year to the GE Rangr setup.
If I was needing CHP equipment, I'd jump right on what Matt is offering here.
