I make my own adjustable coyote strechers with 2 five and a half foot 1x4s side by side and taper the top from about 1 3/4 inches to full width at 14 inches down in a rounded fasion, at the bottom I fasten another 1x4 18 inches solid on one end with one 1/4 inch bolt, other half I cut a grouve for adjustment bolt and wing nut, at the top a 3 inch leather strap nailed on holds the top together. I let each coyote dictate its own size w/o over streching. My buyer is always happy with the fur put up on these. Jeff
