Glad you managed it D.A. What a relief !
If you ARE buying the stainless replacements, do make sure you have a dip of Copaslip on each thread, or instead winkle a tiny blob into the screw thread holes in the cylinder, with a steady hand, which I can't do nowadays unfortunately. Making sure none of the copper lube ever gets near the reservoir cup itself.
No, sadly, nowadays the delicate jobs like poking Copaslip into a small thread-hole with a toothpick is a job for Her Indoors, as a relief for her from her usual daily jobs of cooking, cleaning, bed-making, window-polishing, ironing, washing-up,cat-grooming, gardening, etc.
Back in the day when I often frequented motor engineers' workshops, they used to call me 'The Copaslip King'. Wonderful stuff. Perfect for exhaust clamps.
If a copaslipped bolt is torqued to the right value, it won't shake loose, but you can easily undo it when you need to. And it stops s.s. bolts from rotting into alloy or Mazac or ordinary steel.
