G Wagon door handles

[6 pot]

I have a 716 Pinzgauer that has the same door handles as a G Wagon they all work but they are three are different keys.
I can find the correct Febi part on ebay and other places but not in a set of three. Also my fuel tank cap does not lock so i would like if possible to buy three new lock barrels for my old handles with a matching fuel tank cap and one key for the lot. If that is not possible Three new compleat handles with matching fuel tank cap and one key for the lot.
The Mercedes / Pinzgauer part number for the door handles is 6707600159
The Mercedes / Pinzgauer part number for the fuel tank cap is 0004700430-1
Please point me in the right direction
Thanks
