I bought my 98 12 valve Q-cab new in 98, ordered it from the factory with everything, Leather, SLT, ect. it has 98,000 miles on it and across the US three times. I killed the KDP (tabbed from a kit from TST) which was out about 1/8 inch, and did the seal on the vacuum pump with a kit from Gould gear, also starter contacts from Larry B. I have replaced a window switch and removed the EGR crossover tube (California requirement). I put on a Pac Brake and little bigger injectors for towing my 5th wheel. Total price when new was $34,135. 73 on 11/21/97, out the door including California Taxes and License. I love the truck and am going to keep it till they plant me.
