I'm in the middle of a 96 to 04 marquis swap and was wondering about the harmonic bal/crankshaft pulley. My squestion is which do i use? Use the 96 or use the marquis? The marquis has alittle more weight but other then that they are same about of ribs and everything and belt lines up no problem. They are both different part number but just not sure.

Well I can say the 04 is in way better shape(200k vs 59k miles) and they are the same size only difference was the 04 had a bigger/thicker "plate" on the front of the pulley assuming can dampen more vibration cause of the extra weight maybe?
