Door hinges

Hello I have just bought some door hinges for my series 2a 1971 swb. Have been told that I should be able to find out by the markings stamped on each part as to where they go. Does anyone know where I can find out this information please? The hinges are the type that use the pin bolt set

Have you tried matching up the holes, looks like rear door same front

Nope didn’t think of that lol. I will check them tomorrow appreciate you letting me know. Many thanks
