I looked at the truck, I can put my whole fist and then some over the turbo, so I have the smaller turbo, and I have the 2' intake plenums, so i have mostly early 99 stuff. I would assume that I have early 99 injectors too. I havent looked at the rods yet. If I do look at them, will I lose any oil out that hole? Or do i have to wait to do it when I change the oil? If I did upgrade to the 3" intake plenums, I guess I have to do a whole Y pipe change also, considering that they tap into that....Thanks for the info!!
