Yes, it 8x1.25 and 50mm long.

Tried to use stainless steel bolts. Broke 2 out of 4. One on each cylinder. On one, I managed to unscrew it by hammering a torx bit into it. Just in front of the frame. That was lucky.

On the second, I was possible to remove the receiving part of the tube by unscrewing it from the cylinder and the bolt was brutally drilled.

Now I do not use stainless bolts or bolts from solid types of steel. Now I use studs, as installed at the factory and copper / bronze nuts on one cylinder, and ordinary steel screws on the second cylinder.
