SPHERE STEEL GROMMET .330
Good quality manufactured part, however, it is NOT easy to install. I would not recommend this installation on an already completed aircraft with limited work space. The size .25 does NOT fit over a .25 control cable, try .26.

Yes, 05-01382 will secure an A920 outer housing.
I could not identify an A-760 cable, but if you are referring to an A-1760 cable, the best eyeball assembly to use is one with a 0.240" hole. There are several to choose from this size. You will just need to select the style of assembly you want and then the hole size 0.240".
You will need to drill a 1.125" diameter hole.
If you need the housing to go through the eyeball firewall fitting, then you would use Part # 05-01381.
