The frame is normally assumed to be the vehicle and the V5 would go with it like a normal sale. If you don't have the V5 you can get the DVLA to issue a new one for that frame number the same as any lost V5 and it'll have the same numberplate as before and just need to get MOT once the build is finished. It could be trickier if the V5 has been returned to DVLA with the box ticked to say the vehicle has been scrapped or if it has been recorded as a serious write off in which case you may have to apply for a new numberplate to be issued.
