Yes, you do have a problem there. There are two main types of 'vintage' bridge. The original three straight brass bridges (with their various compensated alternatives) and the more modern non-ashtray type with three screws instead of four. None of these will be a straightforward swap for you. You will probably have to plug and re-drill. From your photo, it looks like your bridge is longer than the Fender one. I would be inclined to stick with it. Problems with a 'vintage' Telecaster bridge - intonation is a com[promise, even a 'compensated' bridge will not work across different string gauges. The more annoying factor is that when you bend strings on a vintage Fender three saddle arrangement, they move sideways and put the guitar out of tune. I have changed away from the stock Fender saddles to a brand beginning with 'G' which offers compensated saddles with a notch to stop the strings moving sideways. The intonation is still not as good as you will get with your individual saddle bridge as the compensation only works in fixed steps. Don't throw the baby out with the bathwater!
