My first Focomat Ic came without the little tabs.
I fixed the helix in position with a with hose clamp. The hose clamp overlapped both the knurled section of the helix and the black painted section of the enlarger - I shimmed the black enlarger section out with a bit of cardboard to bring it to the same diameter as the knurl.
This was simple and effective . The hose clamp held my autofocus in calibration for the 11 years until a ran across a pair of the original tabs.
