Need all the help I can get- Santana 2500 DL, 1990 -info needed

Hi everybody! I have a " Land Rover" Santana 2500 DL, 1990, LWB, 2.5 l diesel ( 45kw).
I would need a workshop manual in english or german!!!
I would like to know what front and rear axles it uses ( want to find front and rear lockers) and where I could find spare parts in general. Body wise it seems that Defender parts could work, but the engine, axles, and so on seem to be different from Land Rovers III or Defenders.... I believe the gearbox is a lt 85 and the transfercase a 230r but with the rest , I have no idea...... Any help would be very much welcome!!!

I think the engine is from Iveco or possibly Suzuki?. No idea where the axles were from though. The Santana is a look alike Land Rover. It was a license built version, using whatever parts they could find that worked. It's not actually a LR. I suspect information on here will be sparse at best.

Just read Wikipedia. It's actually quite interesting in a non LR way.
