Countersunk string ferrules for Custom Tele?

I'm building a Custom Tele replica (the circa 1960 one with the body binding) - are the through-body string ferrules on these usually countersunk or not? If the originals were top-loading, stuff it, I'm doing it through the body anyway :mrgreen:

Also, does anyone use the Seymour Duncan Vintage Stack pairing of half-size humbuckers on their Tele? I think they'll give an original look (the neck pup has the chrome lipstick cover and everything) but the humbucker sound. I'll tap the bridge pup and use a push-pull tone pot for single-coil operation.

Telecaster from 1950 - 1966 have recessed ferrules according to the Duchossoir book. Make life easy for yourself and get the StewMac flush ferrules.

The top loader bridges were used for about a year starting in late 1958. Late 1959 and 1960 usually come with a bridge drilled for both string through and top loading as existing inventory of bridge plates was used up.
