I've looked high and low and don't think anyone makes these. Are there any other Chevy vehicles I can look for that would have them? These are the flat clips that are bolted in along rear drivers side on TPI cars. They hold the fuel and brake lines to the body.

 

Long discontinued and only on 82-92 F bodies, according to GM part catalog. find a guy parting one out and see if you can obtain them. Good luck.
