The ONLY thing about making scrap parts....is they generally take less time to do the second time around! Such was the case with anchor block #2. I relocated the spacer on the new block after opening up the anchor pin hole to the right diameter.
After getting the holes transferred from the bulkhead again....I checked and double checked that I was putting the counterbores on the correct side of the block. Check and double check....it was right. Inserted counterbores....then inserted the nylock nuts and secured the anchor block in the airframe!!!
