How to tell if a bull bar is compatible?

[briar_rose]

I've searched the forum and googled all the combinations of this question I could think of, but I haven't been able to find an answer - how can I tell if a bull bar will fit my Thai build? I bought my 2011 D40 ST in Feb, sans bull bar, and while I'm not opposed to buying new, I have found a Nissan one on Gumtree for a D40 Navara/R51 Pathfinder. Seller has sent me a photo of the model/batch number (F2200-EC000AU ; 707250) but doesn't know what model it came off as he'd planned to mod it anyway. Is there a way to tell with the numbers which bull bars fit Thai vs Spanish built D40?

Thank you in advance
