been a member for a while but havent really contributed much, learning a lot on the fly, love subarus and am tackling an ej conversion myself at the moment but i've come to a bit of a halt with the front CVs. i bought the crossbred brake kit from jeff earlier in the year, installed it no worries apart from the front CVs. the running gear in the MY is from a 92 liberty and im running both the engine and gearbox. in relation to my CV problem, i was under the impression that given that the front steering knuckles were from the liberty and that i'm running the liberty box the liberty CVs would fit ok, but as it turns out they're too long. i spoke to bloke who does CV joints locally and he suggested keeping the liberty inner and outer CVs and changing over the shaft to the one from the MY. but after pulling the MY CVs apart he said he discovered that the MY had 22 splines and the EJ one had 23. my understanding is that the 22 and 23 refers to the outer parts of the CVs and not the splines on the actual shaft. Is that correct? he should just be able to take the inner and outer CVs of the the liberty assembly and put them on the MY shaft, what has everyone else thats kept the ej box and installed jeffs kit done?
i'd really appreciate any assistance

The progression of axle shaft lengths goes MY,L,XT6,1st gen Lib so ideally if going to the later knuckle/hub assembly you should try to go up one in front axle length . Also ideally you should try to adapt to the 25 spline axles because the joints have the largest and strongest races/cages/bearings so more load bearing area and in theory longer life/greatest strength .
From memory there is an L series DOJ thats 23 spline on the gearbox (inner) side and 25 spline on the outer or axle side and you could use RX turbo 25 spline front shafts and FrWD Lib 25 spline CV's . The FrWD Libs used the larger diameter 25 spline front axles because they didn't have rear wheel drive to spread the drive loads over .
In my 87 factory WSM it shows these complete shafts as auto 4WD L and called 95AC23 and all you'd have different is the Lib 25 spline CV joint .
The only possibly hard bit to get would be the 23 spline DOJ inner race section .
one type has the same spline (shaft to joint) as early liberty cv joints
lifted 3" front 2" rear all rolling round on 27" khumo Kl71's
more in progress ie:adaptronic ecu and sc14 supercharger

Surely we have a conclusive answer to this and someone has done this.
I have a brumby with 95 wrx box and ********* brake setup with wrx hubs.
It was 5 years ago that i completed my conversion and i have been using it as an occasional driver. Very quickly i developed a loud knocking noise from a drive shaft. The shafts (which i should have noticed when i put them in are too short) fell off the end of the gearbox stub spline.
What shaft did i use? I cant remember, but i need to know what shaft will suit to pass rego.
Any offers of help accepted?
The horse feed car; 1988 subaru brumby, targa top, and in need of some tlc.
Contact me for reproduction XT6 hubs...and EA82 rear discs.
Now, he told me that all the measurements will be needed to be taken by me and he will take no responsibility if I give him 1mm out and the setup fails. He also said that after the shafts are machined they are sent for hardening to make sure they don’t sheer first dump of the clutch. Hope this helps.
