The Lotus Grand Tourers

Does anyone know a good source for new ones please......
Only need the door locks.....the keys are a bit hit and miss......I think they're too worn.....
So while in pieces ill put some new ones jn
Any help much appreciated
Thanks
Gareth

I will hazard a guess at Morris Marina mk1 for the S1 and for the S2 Triumph TR7. Also very Range Rover ish.

This is TR7 barrel from Rimmers

Marina and Allegro...

I think I've found some.......but the part reference they quote is.......Lucas 345070
Did lucas make locks too?
