I have a 1961 C15, unfortunately I have had to change the engine because it was beyond economic repair. In the past I have had a lot of trouble with DVLA regarding registration of a previous C15. The replacement engine is the latter 1965 engine.
My question is, will I have problems with DVLA changing engine number on the V5, I am fearful that they are awkward and retain my current V5.

Thanks
Mark
