Replacement eyeball fitting/return faceplate

Iam looking for replacement return jet faceplates , but can not find who makes the broken ones i have .  After looking at pictures  it looks very very close to the swipquip  jet that has the 4 screw holes ( 08428 )  except the outside diameter is 2 7/8 inch and the 4 screw holes are 1 5/8 inch apart on the ones i have . Has anyone found a replacement or retro fit for this jet ?
