I am looking at a NOS that is not dimpled and have never did a swap like this before all of my other playfields were restores. Are there any guides I can read or any advice to make sure I put all the holes in the right spot. I thought of a giant piece of tracing paper but wasn’t sure if that would work. I would have to imagine there are variations in playfields especially when there were different manufacturers so things probably don’t line up perfectly if you use the trace method
