This is quite interesting, as you may or may not be aware I am having to shorten my LHS drive shaft. After looking at the OEM diff I found that the drive shaft had been bottoming out due to the addition of camber. So I thought best buy a new inner CV spider coupler and while I'm at it I may as well replace the outer and inner CV boots and circlip. I was quote $499 for spider, $12 for circlip, $65 for outer and $70 fo inner CV boots. I ordered them then thought hang on I only spent $450 on a RHS drive shaft a year or so ago, so I phoned back and got a quote for a complete LHS drive shaft and it was $470. Worth thinking about if you are buying small parts of a complete unit. I now have a complete LHS drive shaft that I can mod too as a spare.
