1988 560SL. Found a bad spark plug wire so I went to the dealer and got a new set. Fastlane and other sites say the #3 and #4 ends must be changed to the angled connector.

So how is this done? I don't want to ruin the wire set. Detailed instruction woudl of course be appreciated. Would have been nice if the dealer parts guy had told me about this. I could have gotten the parts when I was there.
