Spider change not a bad job at all. take your time, print out a few guides from the net, read them over several times before you do it and its really easier than you think. Truck runs 1000% better. I had severe rich conditions. Many of them were probably leaking and the fuel regulator was also probably screwed. You get the whole nine yards with the spider kit. Pretty much like putting on a new carb.
Did mine last year on the 96.
Run the Techron ever since in both of mine.
