Strange part numbers on junkyard parts

Hi,

I finally bought ZJ rear disk brake parts from a junkyard. The seller told me they came off 97-98 ZJ. However, I can not find part numbers I expected anywhere on them.

Here is what I see:
On the backing plate/bracket
3213236R-U
2e72556
3212260-R

On the disk [some digits could be wrong]
2539208

Are these correct parts or did they make a mistake ?

Thank you,
Andrey
