The dashboard has been swapped out for a dx model unit - the dashboard and door cards dont match, the dx cards end at the top of the door and are lighter colour (ivory beige compared to saddle beige of GEM)
The compressor, condenser and tubing isnt original, its hand made desi stuff, the ac lines going into and out of the firewall look like crap. The original are steel pipes. And this uses the oldschool denso 6 cylinder compressor that has unlimited life. I see a sanden 505 or a clone of it. And hand installed stuff to raise idle rpm, the factory stuff is very chunky, literally heavy solenoid.
the fan shroud is for original 4 blade fix fan, factory ac car had clutched fan and a different shroud. You can also notice that the heater pipes are missing from the engine and the factory rubber plugs are on the firewall. (Confirming its a car with no factory ac or heater cooler)
To find out the transmission, look at the ID plate and look next to the text saying trans/axle, the model will be punched as xxxxxx/xxxxxx the numbers before the slash is the transmission and the numbers after is the diff.
