5th gear on the Farmall h and Farmall M is not obtained like the first 4 speeds are. Gears 1-4 are actually different size gear sets that mesh together to change the ratios inside the tranny. 5th gear does not involve gears meshing at all per say. It is obtained by locking the shafts to form a sorta direct drive. (Cheap way to get a 5th speed without adding the cost, weight,and space that another gear set would consume - so it is clever in a way).
When you move the shifter into 5th gear it does not move as much as it does in the other 4 gears. (maybe half as much).
That said you do have a problem. As has been pointed out already. I would check the end of shifter rod (build up and reshape to size with braze or weld as required). I would remove the slop from the shifter (see sloppy shifter fix on ebay). From there I would look at what these other guys are telling yah about the detents....or more likely in the mechanism/splines that lock that shaft for the direct drive for the 5th speed.

When dealing with thinner metals like sheet tin, a long bolt and
