Linkage setup

Ok, got the plates on, shifter pinned in neutral. The rod for 3rd and overdrive is a bit short. It will shift into reverse, 1 and 2. Shifting to 3 its like 1-2 won’t go fully into neutral and won’t let it shift 3-4. 3-4 is barely threaded in and i have to pull the lever back to pin it. So is it the 3-4 rod problem or could the shifter be worn?
