I'd like to start off by saying i used the search key and it was no help.

 so i have never seen an s12 manual drive shaft so i was wondering if the auto and manual drive shaft have the same rear half or if they are indeed different.

i know in the s13 the drive shafts are different , i have a feeling they are different in the s12 but i need some sort of confirmation before i go ahead and start my ka24de and 5spd swap.

pictures of the drive shafts if possible would be nice to for future reference.

Thanks.

only the front halves are different lengths in the S12.
And when doing a KA swap, you use the front half of the S13 driveshaft mated to your S12 rear half.

But, when swapping from an auto to a manual in an S12, OR an S13. It's a very good practice to get the whole driveshaft. Because that way it can be marked as to how it came off, and you know it will be balanced then. When doing a KA swap, you can only pray.

I'm not 100% sure on this, but I think nissan balances each part, not the shaft as a whole. As nobody with a KA/SR/CA swap has said their driveshaft is out of balance

can i use the bolts that hold the 2 shafts together on an automatic driveshaft on a manual driveshaft for my s12???

Im not sure if its correct but I did use the same bolts where the two halves mated together.  Im doing a vg swap which required me to use the mouting plate, between f/r shaft, from the front half of the ca onto the vg front, the place where it mates to the rear half.  Make any sense?  haha, pictures would help on this one. Basically the I had to use the old one because the bolt pattern from the vg shaft wasnt the same as the orignal.  So, swapped it to the original and its golden.

280zx front brake line. To connect the hardling to slave cyl because u will be not using the dampner box that's on mt cars. Do u have a cross member solution and the platethat goes between the motor and trans itself u will need the mt variant
