If you can get the pair together (used) with all the connecting rods then you are good to go. If you buy the locks separately (they do crop up NOS as well as used) then you will also have to find the rods etc.
I got the whole lot of you want? Will be in workshop tomorrow so will take some pics! Bought for my resto earlier in year thinking was needing it but turned out to just need adjusting..... Both front rear & linkage all yours £70 or posted for £80.... long box required!!! Sent from my iPhone using Tapatalk
