Well they gave us a replacement which fitted, on the road again...
MNT thank you Old. Tony if you can tell me more about it so may save me some trouble in the future.
I've learned the heard way that there are countless subtle differences with components between our MNT's compared to the VSK's.
Whenever buying anything really emphasise you have the Thai built MNT. I hit a roo in 2019 and damaged the fenders. My plan was to buy new guards from the wreckers. I was eyeing off some white fenders on a VSK but fortunately the bloke in the yard saved me from my own ignorance ... "nah mate they won't fit 'cos it's Spanish ... I've got a white Thai over here". The outside profile is the same but the bolt holes don't line up. I did discover VSK outside mirrors (without indicator lights) will bolt straight on and the electrical plug is the same.
I also learnt the wider flared fenders on the Thai twin cab bolted straight onto single cab RX which had the narrow flares. I always disliked those narrow RX fenders. My single cab now looks like a proper 4wd. Also I grabbed the door wiring harness from the Thai and power mirrors from the VSK. The Thai donor vehicle had already sold the mirrors. My RX had the manual outside mirrors which were painful.
I recently changed the upper control arm ball joints to 25mm extended. The UCA ball joints are totally different between Thai and Spain. Also wheel offsets are very different so if you're buying rims makes sure they're for an MNT.
So I'm very careful when ordering after doing my own research.
These are useful online parts finders I use all the time:
Catalog Nissan | Genuine Parts Catalogs | PartSouq Auto Parts Around the World
partsouq.com
Spare parts catalogs on foreign cars. Search by vin. Spare parts for any brand of car.
7zap.com
I find I've become so cautious I'll use both as a double check before ordering anything ... I guess it's the "measure twice cut once" policy.
