I thought I noticed a taller oil box on the later 240's in the junkyard, but I wasn't sure. I didn't use the "s" shaped pipe at all, but grabbed two of everything just in case. I used an extra rubber pipe that runs from the intake hose to trap (used on later style) on the oil box-through the intake manifold. I cut both ends off to fit accordingly. I just stuck the trap and holder inside that pipe at the top then fit the last rubber pipe to the air intake hose and to top/cover trap. Everything is clean and fits tighter than the original trap. I didn't have any problems w/ the wiring harness at all. I also found out that my original flame trap was missing the trap part with the small holes.
