they where looking for 5000 at the june sale and only 1700 offered

Thanks Turtledale. I found the publication you mentioned, and in it, it gives the exact same dimensions for skunk, and gray fox and I DO have gray fox boards.... so problem solved.

I just use the metal ones I've had for years now, even ones for coons will work.
Just sqeeze them together more for them extra large plus skunks.

fox and skunk boards are almost the same, bigger skunks are on coon boards, I put up 33 so far,

Well now that we've got that figured out, now I just need to go find some skunks. LOL.
