Fast hitch hitting left fender.

I have 3 cubs but this is my only fast hitch. My issue is that the rockshaft is hitting the left fender where it goes under the fender. I saw one picture where the fender was notched to provide clearance, but I really would rather not do that. Any ideas? Picture is of my setup. Thanks.

I’m a little confused about what you mean by going under the fender. Is it possible that your fender is slightly bent, causing the conflict? Is it possible for you to include a photo of where contact is being made?
 
If you mean the large shaft rubs on the fender, about 4" below the lift rod, I don't think it would matter much, if all the bolts are installed, and the hitch lifts and lowers right.
You could loosen the 4 bolts holding the fender on, and see if it will lift up any.
The hitch is missing 2 quick attach pins, on the large pins the rope is around in the picture.
The left one is a special pin, with a hardened sleeve on it.
The right pin is supposed to be in from the other direction, so the long part of it is out to the right, to attach the lift rod for the Cub 144 Cultivator rear sweep to.
The 2 open holes on the left are for grease fittings, 1 fitting is there, on the right.
Below are pictures of the pins.
The pull bar originally has a pin like in the 3rd and 4th pictures below, it has a hardened sleeve too.

Here is more info.
It looks like the right bracket holding the hitch onto the right final drive in your picture is backwards. It's sort of hard to see it in the picture, maybe it's just the picture making it look that way. I don't know how the bail would fit if the brackets are backwards.
Looking in the Cub and LoBoy parts manual, the left bracket is part number 520125R1, or R2.
It may or may not have a hole in it to get to the plug to check the final drive oil level. Early brackets had no hole.
The right bracket is 520124R1 or R2.
Usually the number is cast into the brackets, you can look at the numbers to see if the brackets are on the right sides of the hitch.
Below is a picture from TM Tractor Parts of a Fast Hitch right side bracket on a Cub. This hitch has a depth adjustment lever, to the right of the seat. Newer hitches have the crank, to the right of the seat.

The brackets at the ends of the round bar the pull bar hangs down on are upside down. They thread onto the round bar. They need to be changed 1/2 turn. Turn them so the are as far onto the threads as they can go, and be the right direction.
I have found that putting some grease on the seat shaft, as you put it together helps it move better.
Below are pages from the 1955 Cub operator's manual showing the Fast Hitch.

Fast Hitch on a tractor
Which version of the FH do you have?
Early style had the depth adjuster lever on the right side. (this is the version shown in the TM Tractor link)
Later style uses a hand crank on the right side.
There are several parts that are very different between the two versions.

I’s hard to tell for sure, but I think the two brackets are reversed. Right bracket is installed on the left, left bracket is installed on the right.
