Hi all.
I have obtained a NOS 1970 interim top yoke, p/n 06-1915, which has a rusty solid stem, unlike 1972 yokes . I want to replace the stem against the 1972 type hollow stem.
Stem diameter is identical, and I hope that goes for the knurled section as well. Has anyone completed a similar swap?
Will a new stem (AN part no. 06-1918) provide necessary grip, or will the yoke require an oversize stem in the interference area?
The old stem will be carefully removed by cutting it below the yoke and by machining a 24.5mm co-centric bore. The remaining "sleeve" will be removed by carefully making a diametral cut with a hacksaw.
There may be other ways ...
