Quoted from pinballinreno:The only way is to attach the rear mounts and front hangers and see how it sets.
Make adjustments to the hangers as needed.
I also add black plastic washers to the pivots for both the head and the playfield to keep them centered so they dont scrape.
Getting these is mandatory so you font scrape up the cabinet during installation:

I think what he's going to need are measurements for the pivot bolts and nuts. Paul doesn't drill those holes. I have an empty TAF cabinet I take take those off of, if need be. Not sure how you'd determine where those go otherwise.
