Hey dink! That looks like my bench at the mo!!! Just don't tell the misses cause I put the bits on the kitchen worktop to take the photo's!
Mine all started because the plate on the bottom of the Drop Link had rotted off and I'd also lost the lower bush

but i decided to take the ARB off and paint it as it was going rusty ...
I wasn't planning on replacing this one, glad I did, you can see how badly worn and mishaped it is
This one is the ARB to Drop Link bush, again you can see how badly mishapen/worn it is (the slit is where I cut it off the ARB)
And just for the fun of it the hourglass shaped spacers from the drop link
All the ones I removed were original VW so I'm guessing they've been on there since day one! ... not bad for coming up to 24 years old and 100k+ miles!!!!
As for part no's it all depends on the age of the van, best to go to VW with your chassis no. in hand but you can also get an idea of whats what from Vagcat. I was informed (not sure how reliable it was?) that the bushes/plates and spacers on the bottom of the drop link are all the same it's the other two that differ depending on the diameter of the ARB.
