The c varient will not fit. Made this mistake myself. Anyone with a b input. I need

I was convinced that i had gotten a shift fork stuck or somthing. But it was just incorrect input shaft. Put old one back and all gears shifted and spun normall and thats when i held then side by side and it became very clear to me

What i had meant was the old in shaft was slotted 180 from itself. "Missing two teeth" the new shact has no slots but that wasnt the issue. The issue was that my input shaft was a 71c in shaft, and the gear is physically wider that the old 71b in shaft. I need a 71b in shaft if you have one.

@datzenmike mini trucl god help me get to work tomorrow 🙂@datsunmike

Figured out that i had 12v shorting the circut with a random wire

I have a 1984 nissan 720 with a fs5w71b trans. The conter shaft bearing went out and i found it cause the input shaft teeth to sheer. Replaced thw input shaft, and counter shaft bearing and gear. Now im having issues overall. When spinning the input shaft in nuetral, the output shaft spinns aswell. 1st and second engage but lock the trans up. 3rd, 5th, and reverse do the same. Fourth gear is not engaging. The only thing i can find diferent is the new input shaft has two teeth where the old does not. (Pics provided) i need to drive my truck to work so please any help. Im a nood and idk if i may have installed the input shaft incorrectly? Thanks for any help

What is this black wire. Also so i have re wired the entire truck. is it 12v going into the fuel guage, then stepped down to 8v for the fuel guage/sender and temp guage/sender? ive wired the oil/ebrake/alt/back lights seperatly on their own fuse. fuel guage and temp guage need to be wired now.
