there are several adjuter shank lengths between your threads and your balls
yours look like long shanks
the 2-3 threads was for adjusters where the balls wewr right below the threads
imho best solution is ball and ball bushrod with cups in the adjusters
that gives you the longest pushrods and highest adjuster cup
yr has written on oiling your balls
it may be in this thread (i did not read lately & i'll try and find it
Reworking the 273 Adjustable Rockers
oiing is same problem
has anyony tried 7/16 tapered or dual tapered pshrods
get as stiff a rod as you can handel
