Thanks for all that advice. Yes its a pain trying to do it even threading it through from the inside as suggested. I did take the door off as I was doing other work. The vacuum lines and cables were secured by ties just inside of the door conduit, as I have now learned to call it, and they were particularly difficult to get at. There are lots online for that part number, are the rears the same? The SL Shop here has them for 6.95. I couldn't find them on the EPC to check the part number for the 116.
