This is the drawing I made:
The plate is 4 inches wide from end to end and is 1/16th inch thick.
I made a side view drawing of the plate by tracing the spare plate I have:
Dimensions:
A= 3/4 inch
B= 5/8ths inch
C= 4 inches
D= 1 13/16ths inch
E= 7/8ths inch
Top view, simple, just trying to show the bolt spacing and hole sizes...
The holes on the edges, on the flanges in the first drawing, are 9/32nds inch diameter.
The hole centers on the short edge of the first image, section A, are 3/8ths inch in from the long side edge. Each of the 2 holes in that end are 1/2 inch on center in from the short side edge, there are 3 inches center to center of the 2 holes.
The hole centers on the long edge of the first image, section E, are 7/16ths inch from the long side edge. As with the other end, each of the 2 holes in that end are 1/2 inch on center in from the short side edge, there are 3 inches center to center of the 2 holes.
The large flat top area has 3 holes as seen in the 2nd image, section C. The holes are all 1/2 inch on center from the side edges of the plate. The 2 holes on the upper part of the 2nd drawing...the one on the left, toward the short flange side, is 9/16ths inch on center from the edge...the one on the right is 11/16ths inch on center from the opposite edge. The 2 are 2 3/4 inches on center from each other. The single hole on the other side is 2 inches on center from each edge...dead center of that 4 inch section.
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
