Just got a used SL30 with the tray, but no DB connectors. I have connectors I can use, but based on the size of the screw holes they use a bushing type screw so they can float a bit and align with the radio connector. Does anyone have a picture of what is used or a part number or source on the fastners? The only thing I can find is the complete kit with the tray and connectors for a good hunk of money.
