Door locks for 1988 TVR Tasmin 280i

[Electraglide2]

I have a 1988 TVR Tasmin 280i. When I bought it here was no key with the passenger side door lock. Its not a problem but I would like to replace the lock. I understand TVR's of this period used Ford (possibly Capri or Cortina) locks. Anybody know exactly which lock I should try and find? Thanks
