yes to fully splined
That's a very good idea if you have the extra 500 bucks to spare. If you do this, i understand that it will be the last time you will be in there. My 99 was in real good shape, so I tossed the split nut and ordered a early full nut and red locktited and staked it 6 times around the shaft. Some say that it will eventually work loose, but I think that depends on how much you tow in 5th. 500 bucks is alot of money, but is also peace of mind. The 6 speeds have problems too, however they are a huge gearbox and just have to be better. Just my 2 cents. Tim
