$20 for Dorman #03315. It's "OK" and it's one of those parts that being plastic, a boneyard example may not be easy to find in good shape. No harm in trying, but the brand new part of only slightly suspect quality is only $20.
Edit - actually hold up. While the appearance is the same, let me double-check that the part will work for a 1994. Just because it fits my 1993... they did change the park brake assembly right around mid-year 94...
Yeah, crap. That Dorman # is for up to 1993. Looks like boneyard it is, for you. Be sure the park brake assembly looks like the one in your truck; I think the pedal pad shape changed, and that's the clue. 10th digit of VIN tag on dash will be an "R" for 1994.
