I understand the bb at 68/70mm is not perfect for the shell but i removed the protective cilinder and the cups attach perfectly to the threaded 73mm shell
The red line you have marked "110mm" isn't the right part of the crank that is 110mm. 110 is the bolt circle diameter - the diameter of a circle that runs through the chainring bolts.
68 English or 70 Italian are the standard road BB shell widths for frames. 73mm is the standard MTB BB shell frame width, and it was adopted along with 135mm rear hub spacing to give more clearance for mud and wide tires.
The OP is trying to put cranks designed for road bicycles into a frame designed for MTB cranks. There are plenty of exceptions to what is considered to be in whatever category these days in terms of the frame, but the crank generally is going to be for one shell width or the other. If you have a 73mm frame, you need a crank with a spindle for that frame.
