E34 front doors question (for 525iX)

[d1mkaz]

I am thinking of replacing both front doors instead of repairing rust as it is still possible to find decent ones for E34, I was browsing in-net in search of compatibility of E34's doors by year and by model, as far as I understood the doors from all models are the same there is a bit of difference between doors of E34's made before 91 and after 91. So I found a pair and asked about the year and model of the E34 they are off but when checking the RealOEM I found out that id nrs. of those differ from iX, example:
94 530i DOOR FRONT RIGHT 41518138006 DOOR FRONT LEFT 41518138005
94 525iX DOOR FRONT RIGHT 41518138004 DOOR FRONT LEFT 41518138003
It is only one last digit but now I am not sure if they actually the same, any ideas?
Thank you

Not sure but the locking mechanisms are different and fit different between early and late, holes are in different positions on the door

Thank you, do you mean early - before 91 and late - after 91? I checked the same year E34 530i saloon and E34 525iX and wonder if someone can advise if 1 digit at the end of OEM number can be significant difference?

Sorry my fault here, somehow I checked US spec nrs here:

94 530i DOOR FRONT RIGHT 41518138006 DOOR FRONT LEFT 41518138005

Nrs for Europe spec cars (RHD) are the same, so front doors are the same on saloons and estates.

Again sorry for confusion
