Classic inside cavity

[fusgtr]

Tom i wonder if the inside cavity of a classic is standard.
I mean is it like the "swimming pool" style or it depends of the pickup configuration?
Is there available space beneath the pickguard if i want to replace a sinle coil bridge pup with a full size humbucker?
(maybe it is post for the tech section...:))

it is not a swimming pool, but it will accept any shape pickup in neck and bridge, and either a single or mini in the middle.

I found a used one but it has 3 single coils and i would like to replace at least the bridge pup with a humbucker...

thnx Tom
