@Xyleff - you don't say why you want to replace that rod, so I'm going to guess based my own experiences along with others I have read about.
That whole piece/assembly with the rod looks like it bolts on, maybe replace that assembly so you would have all the important bits?
If you are having an issue with noise, creaking, squeaking, as myself and others have had, you can try the washer mod suggested by
@RodeoRam above, or...
When mine was making a horrible racket, and after discovering that light weight spray lubes did not help, I used an aerosol, spray white lithium grease. While the lightweight spray lube would work, it would only last a couple days. The lithium grease has lasted over a year and it is still quiet. I'm thinking of using it again while it is hot here, allowing the grease to flow in and around the rod and bushing.
If you really need to replace that rod you might need to visit your local dealer's parts department to see what you can get using their parts manuals.
Good luck.
