Im posting this over at thzcr.com also

Preface I have a zc trans and ex Knuckles And was tryin to figure out
what axel to use I figured that out but not sure what Knuckles i'm currently using

after thinking about this is it possible that both my 90 si hatchbacks came with STD knuckles I doubt that. Are'nt the tha DA knuckles more similar to the EX. If so the EX knuckles would use the the DA. What would you use for the SI and DX. Everybody says use the 90-93 but I know the 2 are different. Maybe we could make a flow chart for trans, axel, knuckle, combos


Axel Tech For 88-91 Civics

STD Hub accepts axels with 23 splines
SI, DX, LX, EX and DA hubs accepts axels with 26 splines

SI, DX, LX, EX, DA, and STD Transmissions accepts axels with ??
SI, DX, LX, EX, DA, and STD Seals have 35mm axle seal diameters
ZC and B series Transmissions accepts axels with 27 splines
ZC R/S Seal part # 91205-PC9-711 (40 X 62 X 8) L/S # 91205-PL3-B01 (40 X 56 X 8)


SI, DX, LX, STD, trans + STD knuckles = Stock axel for STD
SI, DX, LX, STD, trans + SI knuckles = Stock axel For SI
SI, DX, LX, STD, trans + EX knuckles = Same as SI
SI, DX, LX, STD, trans + DA knuckles = Stock axel for SI

ZC or B series trans + STD knuckle = Rightside: Rgt DA axel with STD Outboard Joint /Leftside: Rgt DA inboard joint With Lft STD Outboard joint
ZC or B series trans + SI knuckle = Rightside: Rgt DA axel /Leftside: Rgt DA inboard joint With Lft SI axel
ZC or B series trans + EX knuckle = Rightside: Rgt DA axel /Leftside: Rgt DA inboard joint With Lft SI axel
ZC or B series trans + DA knuckle = Rightside: Rgt DA axel /Leftside: Rgt DA inboard joint With Lft SI axel

ZC or B series trans + Intermediate shaft + STD knuckle = Rightside: Rgt DA axel with STD Outboard Joint /Leftside: Lft DA axel With STD Outboard joint
ZC or B series trans + Intermediate shaft + SI knuckle = DA axel
ZC or B series trans + Intermediate shaft + EX knuckle = DA axel
ZC or B series trans + Intermediate shaft + DA knuckle = DA axel
NOTE : ZC and B series Intermediate shafts are Different in design but splines are the same Correct me if I'm wrong

This option will not work AWD intermediate shaft is to small for tranny
ZC trans + AWD Intermediate shaft + STD knuckle =
ZC trans + AWD Intermediate shaft + SI knuckle =
ZC trans + AWD Intermediate shaft + EX knuckle =
ZC trans + AWD Intermediate shaft + DA knuckle =

ZC Hybrid Intermediate shaft:
88 Integra shaft + AWD Mount = ZC Intermediate shaft

Maybe also the seal numbers for the corresponding Setup would be good
