A419 johnson controler thermowell

Does anyone know of a thermowell for a
6.5 gal carboy that will fit a johnson a419? Like this one: http://morebeer.com/view_product/6667//65_Gallon_Hood_Thermowell

Check this one out.  Just add your own hood.  Cut the small tail on the hood to about 1/4", warm it up and the 3/8" OD thermowell will go in pretty easily.  I’ve got a couple, one mounted in a 6 gal hood and one in a 6.5 gal hood
