CGT on shares bought before Apr 1982

Hi, according to HMRC rule on CGT about using market value for assets bought before Apr 1982, does it apply to listed shares? That means, should I use market value of listed shares on 31 Mar 1982 instead of their real purchase cost for the calculation of gain or loss subject to GCT? Thank you very much for your attention!
