Just swap the rings over, hopefully you or he still has the old Toyota CV joints?
You cannot buy the rings from Toyota as they come on the joint only (which is sold with the driveshaft).
Dave B and Camskill sell the correct CV joints with rings if you need to go down buying new ones again.
yeah i was looking at the parts list and i couldnt see the rings themselves.nope,the old cv joints are gone now.like i sensor cleared and i was ledft with code 31 then after another drive 32 and 31 were dowing.i think i might just pop them out and clean the rings gently with a wire brush
