Is it true that standard Strat pickups won't fit in a Silver Sky SE?

They were tight going through the pickguard but there was plenty of room in the routs in the body.

I had to slightly enlarge the openings for the new pickups in the pickguard with fine snadpaper.

Didn't have to enlarge them much...just until the new covers would slide easily through the openings.

The SE Silver Sky pickups/covers seem to be just a hair smaller than a standard strat pickup.
Thanks! Good to know.
