Hello all. I'm changing my ignition wires when they arrive in the mail. I'm using the stock Ac Delco professional 7mm silicone wires. One of my 4 way wire holders is missing the top portion- the lock half of the clip. I can't find anyone who stocks this clip (just the plastic section) that says "Fits our cars". I do find Napa has one that looks very similar. Wondering if anyone knows which part does the job equally as stock. Is this part discontinued? Does anyone know where to find this part or one very much like it? Thanks Notes. This is the clip by the AC compressor.
