Another detail to look at is the pedal return spring.
The return spring is a coiled spring that encloses the pivot of the pedal. The OEM springs were rather heavy wire and had only a few turns in the coil. These springs are fairly subject to breaking, which tends to make the pedal a little harder for the inching valve return spring to pull back.
Toyota had a running part change on the springs and the new springs are made of a slightly smaller wire, but have more turns around the pedal pivot.
I explain this so if you ever encounter a broken spring you will not think you are being sold the wrong spring, because it will look different than the old one.
