RE: Top Flite AT-6 retract box failure.
Mike.
Here are the dimentions. length, 1.75" : Depth, 1": Inside width, 15/16th: width including the mounting flanges= 1.75" Distance between mounting holes= 1.25"
It looks like it will fit from the pictures but I don't know for sure.
Check out the measurements and if it's close I could send you one to try.
