What exactly are you trying to do mister? It might be easier to understand and help you easier.

I've never heard of a liberty gearbox with a 22 spline cup, its typically 25 spline or 23 spline in the old L's AFAIK, but the rear diff should be a 23 spline cup in the early libs, up to what year I don't know I'm sorry.

If your after a front unit, the Carbie L series front shaft inner cups should do the job as they are all 22 spline on the cup, you 'll need to swap the shaft or the cage in the cup to make it fit. I'm not sure about which one to swap as I've never done it before.

ok on the CV shaft i have,(MYshaft) has a 23 spline(not 22) so the cup spline for a lib g/box is 25.

what model liberty cup will fit my CV shaft?(MY,CV shaft)

another ej22 conversion,lib g/box and MY running gear

Okay, making more sense now.

What you need is the Inner CV cups from an MPFI touring wagon. You should grab the cage too if not the whole shaft to play with. The Inner cup should fit the liberty cage without a problem. The spline count will be the same too, which is what your after.

Good luck

The MPFI cup is only 23 spline, you could use the MPFI balls and cage with a 2wd Liberty cup or an rx CUP.

That's not been my experience - MPFI and MPFI turbo cups are 25 spline, with the turbo cup being larger for the extra stress of the turbo's torque...

Talk to someone that specialies in drive shafts etc they can build any thing that you want in a shaft and have access to all the right information new front drive shafts new cvs both ends ej turbo gearbox standard to brumby outers only cost me $165 each with a warranty. I thought money well spent as he made sure they were balanced
as well.

Sorry Leon, ment to say the MPFI turbo auto cup is only 23 spline, you could use the MPFI turbo auto balls and cage with a 2wd Liberty cup or an rx CUP.

Or just run complete RX shafts
