HELP NEEDED Nissan Terrano door bushes

[Dalystar]

Would any one be able to give me some advice. Just bought a 97 Nissan terrano and the drivers door has door sag. Seems like the bushes are flogged out. So I went to super cheap auto thinking I could just pick up a set of bushes and a pin but they hardly knew what I was talking about never mind where to get them.
Would any one know where I can get them and if it's s big job to replace

Is it a WD21?

Or an R50?

If it's the former bushes and pins are listed on Trademe, cheapies and genuine Nissan

The latter I'm pretty sure don't have replacable bushes so you'll need to buy the whole hinge assemblies

Thanks. It's the R50 model. I wonder is it possible to grind out the existing and use the WD 21 pins
