'71 RR Side Marker Acorn PAL Nuts

[ct71rr]

Hello all, does anyone have any acorn pal nuts used to mount the side marked lights on a 1971 Road Runner or know of a source for them? I can't find them on the internet. I took a chance on the '70-'71 Cuda nuts but they are smaller.

This is for the '71 RR:
