Mine is an original factory battery tray....not installed...the hole is 1/2 inch from the inside edge, and is 5/16 inch in diameter. I have a picture available, if needed........The hole is large enought for slight error since the welded nut threads on the support are much smaller.

Thanks, Jerry. Exactly what I needed.
