I am not exactly sure about the clutches, but I just put a Centerforce clutch in my 90 240 off of nopi for under $200.00, but when I did they asked me if it was a 89-90, or a 91-94, they had different part numbers, but I was told on here that a 90 transmission would work for a 93 engine, so I am just going by what I see, but it appears that the SOHC and the DOHC have different clutch part numbers, so maybe it's the fact that the DOHC puts out a little more torque, or they are just trying to make more money, anyways, as we all know, the clutch bolts on to the flywheel, and as long as the transmissons were compatible, and the flywheels are the same, I couldn't see you needing a different clutch, just a new one if needed. But that is the opinion of a light repair mechanic so, I do not know about 95-98 240's, so I am pretty sure I am right, but get a second opinion, if I helped at all! Laters.
