okay, we know that in 82, the 1800 4wd had the smaller clutch 200 mm, and also the flywheel and release bearing are smaler than the 84+ 1800 4wd...

83 was the "switch year", in that the GL wagon 4wd, got the front vented rotors, and the larger 225mm clutch and release bearing. (input shaft is bigger on tranny, and the bearing holder is different)

the 83 Brat GL though, still had the solid rotors, and smaller clutch.... (I just pulled original Subaru parts off a 86k '83 Brat GL to verify....)

 

the question: Did the 83 Brat still have the lower gearing for 3rd and 4th, like the 82 Tranny?

Negative.

 

 

I think that only the 81-82 and possibly 80 (if they made it dual range) had the shorter 4th gear.

 

I can say I've owned all the years of gen 2 brats till 86 so have had a chance to learn the trannies. But the 81-82 wagons had the same dual range as the 82 brat.
