Picked up an old quick change housing over the weekend trying to find more info on it, pulled the side bells off there stamped D-1025 inside, QC housing has no markings or part numbers. Was hoping someone would know what company made the side bells from the part number, I'll add some pictures of the housing tommarow, its kind of an odd one 3 ribs on each side, smooth top like a banjo center and has 4 ears around the cover area.
It does appear to be a thru-axle sprint car style setup. If the bell pattern is the same as other brands, you might be able to use axle tube side bells, for a more conventional setup.
