I had to create two sparkplug pass-through plates because the first one came out terrible. The second one looks good. Getting 6 of those big holes in alignment and with uniform spacing proved to be easy once I used graph paper to create a template. I also had to create two oil dip-stick retainers. On the first attempt I let go of the hot piece when I was drilling the large hole and it came out off-center. For the second one I used a small hole and then the reamer. The second one looks really nice and I couldnt be happier with it. I also reamed all four of the Accel bracket washer/spacers to fit the top cover SS pan head bolts.
