Hello, trying to remove the upper shift shaft on a 1964 Mercury 850. I've removed the power head and the spring/clip the attaches to the shift rod. I can lift it up about 1 1/2 " then it stops. Don't want to apply any force in case there is something on the end that needs to be removed. From what I can see it is all one piece that just slides over the lower shift shaft. Any help would be greatly appreciated. Got to get it out to remove the swivel bracket to free it up from corrosion. Thanks
