Hey Scott, I may have what you are looking for. Back around 1985 I made up some templates for the 32 mm system to use with a plunge router with a guide bushing. Back then, I couldn't drag any of the local shops from using face frame, so I quit wasting my time trying to market them.
They are made from 1/2" apple-ply. The one for uppers is 12"x 48" with 3 rows of holes. The middle ones are for 9"deep bookshelves. All of the holes are chamfered to make it easier for the guide bushing to drop into. It works best if the router base has a straight side rather than full round, because rather than picking the router up going from one hole to the next, I tip and drag it. This way the bushing drops in quickly on its own. I normally can drill about 90 holes in a minute when I get warmed up using muscle memory.
The base template is 34.5" T x 24", and has a 4" toe-kick cut in the bottom front for easy marking. It has all the holes for a door and drawer, plus shelf pin holes, or 3 and 4 drawer stacks. So I could screw all the hardware on to individual sides laying flat on the bench before assembling the carcass if I choose.
Its easy to use once you get the hang of it. I'm still using the same router that has always been set up for 47 years.
Drop me an email if you think this sounds good to you.
Oh, the way I normally use it, I don't have to keep track of left or right hand doors, they are drilled the same distance from the ends so can flip until drilled for pulls.
