Accelerator Pedal-Cable retainer plug

Guys, I'm looking for a source for the little plastic cable retainer plug on my 71 Charger's accelerator pedal. I had mine as recently as 2 weeks ago but in the thrash to both get the car running and moved 400 miles I seem to have lost it. I've searched the web just about every way I can think of but only seem to come up with the rather different and larger looking GM retainer.

That's the one, definitely kicking myself for not doing a better job of keeping track of mine after seeing that price!

can you fab up something that will do the job?

I would look at using a small screw or bolt ( #6,#8,#10)and nut with flat washers to keep it in the hole
I left that plug out on one of my old race cars, 1970 Hemi Cuda 4 speed car, and the dang throttle cable fell out of the slot after doing a dry hop after the burn out I put it back in after that
