Help Needed!!!

New Process A903 1962-72 Cars & Trucks Inquire

Cast iron, top loaded case with side shifter linkage. Non-synchronized 1st gear with aluminum ring/pin assembly for 2nd/3rd. Main shaft 1st/Reverse gear has 29 teeth and the cluster gear has four steps.
It sure seems like I read some where that 2nd gear is synchronized !!
I wish I new more about helping you.
Could the shifting fork be wore or bent or even broken on one side ?
I hope a tec will jump in and give you some help.
