3) I now wonder if the threaded holes in my pads are in the correct location. Can you give me a measurement of where the threaded holes are in relation to the front and bottom of the block?

Now that I have this plastic block I my as well make it correct.


Yes 7/16.
Yes crank centered
left or driver side 1.600 up from pan rail too center of hole (lower hole)
4.700 back from timing rail (front lower hole)
Right side 2.050 up and 3.00 back (front lower hole)
