Or you could try this mod.

I think I may do one of these mods when I run out of spare standard CV's. 
i'm already running two left hand side shafts, but the left hand shaft on the right hand side bottoms out sometimes. i need to widen my vit a la hagen widening.
i know all about the chopping bit, but how does the outer fit into the vit hub, lockout, and spindle? how are they the same when you need to machine out the spindle when using yota shafts?
EDIT: ok, ok, i got it now. you chop the inner 3 bolt flange, and you chop the outer bell to use the outer shaft. and you need to weld them onto the donor shaft. ok, i see now.
so now i need to go and measure how long my cv shafts are, and see if i can find some donor shafts the same-ish length.
