Hey guys of the first generation, I'm taking the plunge with this computer, and I hope that you guys will have some patience while I learn my way around this thing. I've read a lot here and learned a lot too. I do have some changes I've done to my truck which I haven't seen here and would share if anyone was interested. For instance, eliminating the pin on the nut on the rear axle with spicer nuts (2) to set backlash. OTC nut wrench lenghtned to tighten the early nut for the 5th gear fix on the NV4500. This is a great forum. Later guys. Tim
