Replacing a Fender 57/62

[Prawnik]

I love this pickup in the middle position of my rosewood board Strat, but I want something with grey Forbon.  

For some reason, this guitar thinks it's one of Jimmy Page's Les Paul Standards, and I want to keep it that way.  So which BKP would be closest to the Fender 57/62?

Mother's Milk all the way - although an Apache custom made with Alnico V magnets instead of Alnico III may be nearer to a real slab board era 50s Fender pickup.

Thanks!  FWIW, the guitar itself is a rosewood board 1970-1971 Strat that I made from parts.
