1971 wiring harness straps

[25C 70]

I pulled the front clip off of my 71. To remove the wiring from the front inner fenders I had to break the plastic harness straps holding the wiring. I am trying to find the exact style that was used on this truck. Everyone sells a 376914-s. My straps do not look like these, one end is pushed into the inner fender, then the other end of the strap has a pin on the end of it. This pin is then pushed into the end that was pushed into the inner fender, locking it in place. Anyone have a source for this type of harness strap?

This is what I bought from Carolina Classics F100:

That's them. 8272 made by Auveco. I think my local auto parts store carries that brand. Thank you.
