Homemade DSSR (need measures)

I'm about to do some work under the chassis and i'd love to upgrade my ssk with a dssr.



too expensive to buy a new one in USA and too simple to say "i can't do that"..





can you provide me some measures that wll help me in this project?

i can retrieve some from OEM linkage, but i want to be 101% sure.

i mostly need the pivot clearances and the terminal U parts.





any advice on bearing or similar hints will be appreciated





Thnx in advance
