Unless someone tells you different, there are three things you can look at. First check for any nylon bushings that are worn down or cracked off and possibly missing. The clue they're missing is some connection between two mechanical parts will have a lot of play when you wiggle the pedal by hand.
Next, a common source of that squeak is the return spring where it hooks around the attaching points. Those should be greased, and are usually overlooked. Something thick, like axle grease, works good for that but don't be too generous as it likes to travel and makes other parts messy.
Look at the connection between the push rod and pedal. If you can feel it creaking there when a helper pushes the pedal, that's the point to lube. In some designs it's hard to get the grease inside to coat the entire joint. Chrysler has a dandy product for that called "Spray White Lube" in a spray can. It is a lithium-based grease. It sprays on juicy so the liquid flows into the joint and takes the grease with it, then the liquid evaporates and leaves the grease behind.
If you find the push rod squawking where it slides in and out through a rubber boot or seal on the firewall, use Silicone Spray Lube on that. It goes on like water, then evaporates and leaves a film of "slippery" behind. Works real good in the tracks of sluggish power windows too. Chrysler also has that along with all other manufacturers, and you can buy it from auto parts stores.
