I had trouble finding an ECM tray to fit the 4.9L Cadillac ECM thats in my Fiero. Joe told me that the Duke 4 cyl tray fits but I could not locate one. I purchased the steel GM early LS steel brackets on eBay and used them. The holding points were nearly the same. Can't say that they will fit your application but the are available and cheap.
I just flattened the lower tabs so that I could screw the ECM bracket in place.
