...well were to start, guess first I can ask my question I am installing a daystar 2 inch coil spacer on a 99 2500 and would like to know if there are any tricks to installing them. Then theres my 2000 off-road with a cracked transfer case(and the truck hasn't been put in 4x4 in 8 months)

hmm, and my transfer case siezed up at 61k miles (but I think it was tranny indused) Have fun, I got mine at cost for $740 with shipping from detroit.. but then, it is a np231, I have no clue which one you have.
