Infrared Gregory kiln

Hi, I am the inheritor of a Gregory Kiln manufactured in 1960 by
Gregory Kilns of Cleveland Ohio. I recently took the kiln apart in
order to replace the infrared bulbs which are the heat source. In
classic situational comedy style, on putting the kiln back together I
am left with two parts, one on each side of the kiln. I cannot figure
out where these parts fit. Has anyone out there heard of these kilns?
Does anyone have one and is it still in use? Any help would be
appreciated. The company that manufactured them seems no longer to
exsist. Hannah M Voss, e-mail, @Joseph_M_Voss.
