Next on my list is the Circle D 2800-3000 stall and the OEM 4:10 gears w/ LSD can I ask how much all the parts and install for the OEM gears were? Did you order the gears yourself or went to them and asked?

Far as nitrous I plan on spraying my truck as well(75-125 shot), when I get my PCM back from B&G when they tune it for the 93 octane, no Tq management, raised rev limiter, and etc.. Far as plugs you need are 1 step colder. NGK7787 or Denso 3381
I ordered the parts through my local Dodge dealer where I bought the truck. The Parts Department called Dodge to make sure they ordered all necessary parts to go from my old ZF 9.25" 3.55 open differential to the R/T ZF 9.25" 4.10 LSD, i.e.- LSD carrier, all bearings, seals, ring and pinion gears, etc. The total for all OEM parts was $985. I had my transmission shop do the installation because of their established reputation for technical expertise. They charged about $350 for labor and synthetic fluids. The new LSD gears work flawlessly and silently, and provide higher truck performance. I was torn between 4.1 and 4.56 ratios. If needed later, I'll install Yukon 4.56 gears. My parts list is attached. Hope this helps.

About your spark plug recommendations, aren't they both platinum plugs? If so, a few 3rd/4th gen guys have complained about negative effects (misfires and failed coil packs) with platinum plugs. Know anything about that?
