Re: 71C trans - Z31 and 240SX full gear clusters can interch

awesome! glade i found this! my buddy is parting his 240sx out with a 71c and i would like to swap that gear box into my red 86na with a 71c. Just to make sure i read this right all i need to do is swap the bell housing right and my 240sx b&m shifter i i bought years ago in my 71c should fit in this one.

Bell housing swap:

Slaves from z31 and s13 are nearly identical. Bolt spacing is the same. I've bolted BOTH up without issue.

240sx FRONT SEAL PLATE has the pivot ball in the wrong spot for the zx slave. You have to use the front plate that came with the 71c in your zx.

RB20 71c's have the same pattern and bolt up to the bellhousing.

News to me the s14 71c was stronger than the s13. Good info. Great thread.
