original gn equipment

Does the 85 gn have the same rear end with (g80) posi and the same gear (g42) ratio? Is there anything unique about the 85 grand national?

In a word........NO. Same option codes as any other.

Unique things about the 85 GN......

1) 2101 made that year
2) 1st year for the cloth seats that most GN's have
3) only year you will find a hot air block with a 20 bolt pan (late production year models)
4) only hot air with a factory crap master (again late production year models)
5) 1st year for the electronic climate controls???

...not sure on that last one...(I know my 85 came with them from the factory)

My 83 has the "climate" control Keith.:biggrin: Taking it out and selling it to MrsFastnasty when I change it over.

A master of which factory crap?

My parts catalog claims "2nd design" '85 motors had a Thermac air cleaner, with a thermal vacuum switch installed (looks like) in the water outlet instead of a thermostat in the cleaner housing. Can this be true?

There are also legends in the wild about the '85. Like the one that claims you could get one from the factory with a distributor, running MFI instead of SFI.
