Hey, no problem. I suffer from the fat finger syndrome and an iffy memory.
What would you like to know about the Dynatracs? There's lots of information on this website from members with step by step procedures with pictures. There are other makes such as Yukon and EMS and others that I just can't remember. If you decide to to go with the free spin kit, you may also want to consider the stage 2 kit and replace the ball joints while you have the front end apart. I can't remember if your truck has the CAD, but the stage 2 would eliminate it. There might also be a slight increase in mileage, but unless you really pile on the miles, you won't recoup your costs for a while, if at all.
I went with the Dynatrac stage 2 kit and ball joints and I'm pleased with it. The truck rides nicer and the 4WD engages instantly. I was fortunate to find a rust free truck that I plan to drive until the wheels fall off, so personally it was worth it for me. I also did it for the peace of mind over the unitized bearings. If I was one of those guys who flips his truck every 2-3 years, then obviously I wouldn't bother. I would just put up with the factory unitized bearings, which some guys like and have gotten very good service with.
I hope I answered some of your concerns. If you have any questions, just ask. These kits have been available for quite a while and there are some very knowledgeable members who have installed more than one kit.
