Yes not good sales service. Unfortunately, often aftermarket stuff requires more than 'bolt on'.
As a matter of interest how much did they cost 'landed' at your house?

They are beautifully made
This makes me thinking. @franky I think there's no thrust bearing, right? There's only the spacer between the pillow ball and the spring hat? This way the pillow ball takes all the loads, but I think that's fine.
I like this approach, this could be easily done with stock springs, too.
Around 200-220 €.

the bearings in the VA motorsport look to be about 3x the size as the ones you've got, if not more. Also there's a roller bearing that sits on top of the spring under the spring hat.

I don't have any of the current set up but I've had a look in the Datsun Stores and found, the damper - spring hat - thrust bearing - adaptor - non adjustable spherical bearing top mount I was using, I have to stress this was all used with a 2-1/4" ID spring and not the OEM style/size of spring and its years, 20+, since I had the OEM stuff on my car so having familiarised myself with it we might have a solution for you......
.......using the OEM spring hat and the OEM thrust bearing with an adaptor, similar to the one I was using, onto the spherical bearing in the new top mounts you have?

with these you would.
And with K-macs?

Thank you for those great pictures! I did quite a lot of research during the past days, and the following are my findings:
1. The guy I was talking to from silvermine doesn't seem to know a thing about their product: No, the spring hat doesn't grind the bottom steel plate as a spacer/adapter only contacts the inner race of the pillow ball
2. In theory, proper pillow ball camber plates don't need an additional thrust bearing. The reason: If they don't bind (which I would expect of teflon bearings), they allow full rotation (steering). The additional thrust bearing would be just a band aid in case the pillow ball doesn't rotate like it should
3. Even in your case: There is a thrust bearing, yes - but still all vertical load gets transferred into the pillow ball.
I might be missing something, but I am going to start with no additional bearing. The only change will be that I will manufacture a better fitting spacer/adapter which adapts to the stock spring hat.
