3 bolt and 4 bolt Fender necks

[Mr Fudge]

I have swapped over and dabbled with a few 4 bolt straight swaps. Very straight forward so far. I have a major urge to try my Marcus sig 3 bolt neck on a US standard body. I dont want to drill any holes in the Marcus neck as this could screw up a resale price etc... Seems a more obvious thing to put the holes (or extra hole) in the body neck pocket. Any body done this. Am I making major assumptions or mistakes.

Cheers.

There's only one assumption that I can see, which is that the top 2 holes (on both necks) are in the same position. I don't see why they wouldn't be, but you never know.
I suppose the best way is to whip the both off and line them up and have a look....
