Well I got a t-case from Peter Humblias and not thinking he has a SY well Syclones have a different spline on the rear drive shaft than the Typhoons so the tranny shop is going to send my rear drive shaft to a shop and have it re-built with the right splines on the shaft of the drive shaft....Damn I wish I had known this before I would have ordered the aluminum shaft from mccoys for the syclone for my typhoon...Any way go figure...
