Will a classic still be able to retain its original registration if heavily modified underneath?

My daughter has a 1954 Standard 10. Her boyfriend is carrying out major mods by fitting Mazda MX-5 front and rear subframes complete with engine, gearbox and all the suspension. Will the original registration still remain or not?

You should be able to retain the original registration, but you must declare the modifications to your insurer and to the DVLA. However, the car will be considered "substantially modified" and will therefore not be MoT-exempt.
