I have an 88 XLT w/5.8 EFI.
The plastic piece at the end of my throttle linkage where it connects to the throttle body has broken in half. It's now binding up and sometimes not letting the idle return to normal. I cannot figure out how to replace only the plastic piece. Do I have to replace the entire throttle linkage from throttle body to cab?

 

For all of you who are curious. The accelerator linkage is all integral. If you break any part of it, the whole thing has to be replaced.
You can get it from autopartsgiant.com for $32.18. If you can't wait for it to be shipped, expect to pay about $80 for it at the dealership.
Peace.
