I ordered the 300ZX CV Conversion Package from Ross Corrigan (Modern-Motorsports.com) awhile back. I then went ahead and bought some used 300ZXT CV Shafts from a junkyard. The problem is that they were pretty beat up so I decided to use them as cores and buy new ones at Autozone. I ordered the part as a 1989 300ZXT but when it arrived, both ends had splines instead of one side being the 4 bolt model. The attendant looked at previous years and they're all listed the same part number. Am I ordering the wrong year/model?? Can anyone let me know what exact model and year that the correct CV shafts are to use for this CV conversion pacakage?? Please help! Thanks, -jAy
