digger jr Posted March 8, 2018 Report Share Posted March 8, 2018 Did Catek make 3 hole center disks for the OS2? Thanks Quote Link to comment Share on other sites More sharing options...
rjnakata Posted March 8, 2018 Report Share Posted March 8, 2018 (edited) OS2 started with 4x4 + 3D disks and then changed to 4x4 only. 3D compatible disks are out there - it's hit or miss. Edit: to clarify there exist 4x4 disks WITH 3D combined. They later moved to 4x4 only. Edited March 9, 2018 by rjnakata clarity Quote Link to comment Share on other sites More sharing options...
Beckmann AG Posted March 8, 2018 Report Share Posted March 8, 2018 If you delete the bridge from the parts sandwich, you can use the OS2 upper on an OS1 lower, and the OS1 lower was dual pattern, while the corresponding FR1 was 4x4 only. (The OS1 base/spherical nut should be easier to find) Quote Link to comment Share on other sites More sharing options...
