Used cheapo screws-worked ,but
Thanks guys.I tried some cheapo screws-filed the threads off.They worked.I might see if I can chase down the park replacements-they look a bit coarser threaded,but might be worth a chance.
However, I had the correct Campy tool to take the right-fixed cup-off,but I have torn it to shreds, but I can't get it off.
I clamped the campy tool on with a vise so it wouldn't slip. It didn't slip, it just carved the aluminum out-shaved it off.
I then drilled holes in the cup and tried the LT side tool on it-snapped the screws right off of course.I then tried another tool-for snugging down the disc on a grinder-drilled holes -it bent that tool.
The BB was nice-1977 SR titanium spindle-everything but the fixed cup is still nice.
It is a 68 120 English threaded.
It hasn't been off since it was installed in 1977. Thanks,Charlie
