There were two factory tools:

216: J-969-2

235: J-1646

I only have dimensions for one of them, and I'm not sure which it is. The diagram I have in an old Motor manual lists the dipper height from the oil pan rail with the rod at the bottom of the stroke at 3 29/32". The same tool measures the trough depth at 3 5/8". The 235 will have a longer dimension than the 216 for both measurements because of the longer stroke.
