I have checked the distance the rod is extending from the booster when the brakes are depressed fully.<<

I tried to reread all the posts and I'm not sure how the booster pin length was checked. The retracted pin length is what is important and must be checked.
Loosen the MC and space it away from the Booster with a couple of thick washers or anything that will temporarily separate them. Try bleeding again.

Almost certain to be this ^^^^.

Remove the nuts that secure the master cylinder to the booster. Then slowly push the master cylinder along the mounting studs until it's seated properly in the booster. If you feel any pressure at all the pushrod is either too long or not fully seated within the booster.
