P90's [Soapbars] are generally slightly larger in width and depth,[only a few mm's , but enough that you wouldn't want to tackle it yourself with a router with a very thin maple top, hence the request ]
It depends on manufacturer, but basically there is a standard.
I prefer Kinmans P90 plans, as they cover every possibility.
I've been thinking about doing it/altering it [my ES-1] manually with a "Cut to Cut ' method technique as used for inlay, as in you cut with a scalpel where you want the final cut to be, then use a chisel to cut up unto that, leaving a clean edge.
The Dog-ear pickups on P90's are exactly the same, only the mounting holes for the plastic covers differ [same inside, different covers]...they were used originally for the Gibson L5, I think the reasoning was that since the spruce tops of the L5's had very straight grain, having any screws close to the pickup cut out, would leave the top susceptible to cracking down the grain...they were correct, that's exactly what happened on the early none dog eared P90 equipped Gibson Archtops.
I've measured my ES-1 kit against my Gibson ES347, and the F holes are quite a bit narrower, and absolutely NO way you could get a full sized pot through the ES-1's F holes....seems the ES-1 is modelled after the original ES-335, which suffered the same problem for the Gibson employee regarding wiring them up, that's why Gibson change the block running down the inside of the ES335 so it left a gap at the bridge pickup area, so it could be wired easier through there, rather than through the F holes.
