I had a look at the pic I took of my mate's Mexican Tele and compared it's scale length to the one on my custom Tele and it looks like it ends up at about the same point on the bridge, that got me thinking about how I could fix the issue with the string holes being in the wrong position on the bridge and the best solution I can come up with is to use a round needle-file to lengthen the hole so that the pre-drilled string holes in the body are clear, fortunately the needle-file I'm using seems to be working okay with the metal that the bridge is made out of, although it will take me some time, I need to lengthen the holes by about 3mm.
I'm just in the process of marking-out the centreline of the neck so that I can position the bridge correctly so that the back and front-edge of the bridge are 90 degrees to the centreline, which is important to get right since it throws the intonation at the 12th fret out of whack and just makes the guitar look a bit wonky, on the Squier Tele body, the bridge wasn't positioned so that the back and front-edge were 90 degrees to the centreline, they were actually angled a bit.
Sorry if I seem to be a bit nit-picky accurate about this, again I blame it on my apprenticeship as a fitter and machinist, anyway, I measured the width of the neck right at the start of the scale-length and used the calculator function on my computer to divide the measurement by two, this gives the first neck centreline point, which turned out to be half the neck width, or about 20.7mm, next I need to do the same at the other end of the neck where the last fret is, that gave me 27.0mm, I marked both the points on a piece of blue 3M tape at each end of the neck, that gives the two pints for the neck centreline, all I have to do now is use my 600mm steel ruler to mark the centreline on the body, to keep the back edge of the bridge at 90 degrees to the centreline, I'm going to use my Stewmac string action gauge because I know that all four corners are at 90 degrees.
And then all I need to do is mark the positions of all the mounting screw holes and drill them to the correct depth and size.
I think I've got it right....I checked that the centreline of the bridge lined-up with the centreline of the neck and it looks to be spot-on, I used my 600mm steel ruler to check where the edges of the fret board line up and they line up to within 1mm of the two e-string pole pieces on the bridge pickup, so it's all looking good, the last issue to sort out is getting the nut height right to give the correct 1st fret action according to Fender specs, and after that's fixed I can then go ahead with wiring-up all the electronics before putting a set of new strings on the guitar, prior to doing a full set-up on it.
