In the HDI models, I've read that that pad was used to mount the Emergency Microwave Emitter, which only came into play in the rare and unfortunate instances of HTR - - Hamster Thermal Runaway - - to prevent overboost.
It was rather crudely referred to by laymen as the PGTW* system.

Rotaries don't strictly need them, because of their naturally low NOx. It's hard to get combustion temperatures high enough for NOx to be a serious concern, especially with the thermal reactor "make it run super rich and then burn the rest off in the exhaust system where we don't have to worry about crevice volume issues" emissions controls.
Trufax: I nearly baselined the smog test station with my '80 when it was stock. The thermal reactor system worked *good*. Just not so fuel efficient.

Of course not.... because 1973 was when the NOx emissions standards went into effect, so many/most cars received EGR valves that year. Same as it ever was.

That infamous shift ****
I did not see anything in that wonderful assortment of parts that I can't live without, except possibly the new shift ****. It obviously belongs in my 84 FB which is shown here, has a totally stock interior including the original stereo, except for the boost gage:

Yep; kind of the whole "government-mandated 'engineering innovation' concept" in a nutshell. When to try to force a new performance mandate down the throat of an existing technology, that's usually what happens. Everything else becomes secondary.

Obtanium!
Rare do we see something for our cars go from Unobtainium to Obtanium, but I'm here to testify:
As mentioned in the 'do today?' thread, Rear-bowl carb floats for Nikki carbs are once again on the market, after having been NLA for many a year. No longer.
I got one. Just in time for my carb build, too.
