You can order a catalog of Chrysler service tools from SPX -Miller.
Their phone # is 800-801-5420.
But the two tools you listed, you really don't need them. I've installed many sets of 24Valve injectors without ever using those tools. (an injector removal tool for the 12Valve engines is usually a major convenience, though)
You can find a pair of long, needle-nose pliers with angled tips at AutoZone or any Lowe's or Home Depot.
Use a bolt from the intake air horn that you removed, threaded into the top of the injector, and the pliers turned upside-down against the bolt in a lever-type action, and it'll pop right out, without a lot of force. You'll need to pull back the connector tube slightly as you pry out the injector.
The money, in my opinion, would be better spent on a torque wrench and 19mm crowsfoot wrench for tightening the fuel lines. (you also need a shop manual for your truck, it lists the torque specs )
Tip: Do not use the flare nut fitting to pull the fuel line towards the connector tube, when re-installing the fuel lines. Instead, hold the fuel line seated in the bowl of the connector tube, as you snug down the flare nut. They can go off-center rather easily and get deformed when you tighten down the nut with a wrench.
