Turke, �
These are dimensions that were reported to be 3A sized hood blocks, by a fellow at the 2A page named Bluax.
draw a picture of a rectangle on your paper 4 5/8" L x 2" tall x 1" wide. �11/16" from the left is dead center for your first hole. �Continue on and again from the left side measure 3 5/16" for dead center of your second hole. �These are both 1/4" holes drilled completely thru the width of the block. �Now we will enlarge these holes to 5/8" to a depth of 1 1/4" otherwords, countersink. �When completed you will note that both holes are more toward one end of the block and are NOT evenly spaced from each end.I actually modified mine a little. Mine are 1 1/8" wide and 2 1/4" tall. �Taller because I wanted a little more clearance for the windshield wiper arm and wider because I wanted them to look a bit more stout.
