05 Diamond Victory has IF4 module presently,whats it for and which one do I need for 27.5 D/L? The dealer said it the right one but I think it was for 29"d/l.None of his "I" modules would fit due to different bolt pattern so he called it good! Only gave him the heads up a week and a half ago so he could check on that so guess I have to depend on the group to help now!
