Front and rear inner cv joint sizes

[WidowmakerS2]

Hi,
Does anyone know if there's a difference in the front and rear inner cv's?

[gnutz2]

Pretty sure they're the same part, they both measure 107mm diameter but I've never checked the spines before.

depends.

in USA they are all 100mm flanges front and rear.

in UK i read that the 4cyl are 90mm, the 5cyl N/A are the same USA 100mm, and then the S2 3B/ABY are 108mm.

and my searches have concluded, FWIW, that the rear diff is all the same, except for the vent breather and the flange size. internally the same.
