Yes, it is easiest to use stock TB rubber bushing as a seal, but i dont think it needs any more support.
I plan to make M10 bolt holes small as possible, maybe 10,2 or 10,5mm, so there would be less slop.
Also if making from 7075 T6, whole system can be little slimmer, due to the strength of the 7075.
How much should there be distance from the housing cover inner surface to arm attachment surface? Springplate is 4mm thick, maybe this is about 5mm?
One my finnish vw fellow said that these uniball systems would last longer, if at the inner pivot would have bronze bushing or bearing instead of rubber / urethane bushing, but wonder how rough the ride would be then
