Manual Trans Speed Sensors S13 vs Z31 N/A

[UNISA JECS]

Ok guys need some help here, hopefully someone has a Z31 M/T speed sensor and could compare the bore diameter to that of the S13 M/T speed sensor.

Now your probably wondering what im trying to do, will I have a 97-01 Q45 VLSD with a 3.692 final drive which im going to install into my S13 but I want my speedo to be accurate or atleast close as possible, so after doing a little searching on Nissan FAST I was able to see that the Z31 NA M/T and S13 M/T both use the FS5W71C transmission's duh.

I also know that the Z31 comes with a 3.700 final drive which is close enough for me (3.692), so i wanan get my hands on a Z31 speed sensor from a 3.700 final drive equiped FS5W71C Z31 and see if the speed sensor fits which I think it should since there both the same trannys and I have no reason to believe the casting of the rear section shoudl be different.

Add some more pertinent info here for comparison sake:
