Used 4 speed

First off, first time poster long time reader. Lots of great info on here. I took a gamble on a used a833 while converting my 69 barracuda to 4 speed. Im having issues with it getting stuck in gear. I’ve gotten stuck in just about every gear but first. Once I realized that in my hodge podge group of 4 speed parts I acquired that my 3/4 shift rod was from a 67-71 chevelle by google search part numbers and my 1/2 shift lever was from a Muncie I thought I had the problem nailed. Got all linkage correct through brewers but I still have issues. While popping side cover this evening to pop it out of 4th gear I noticed my shifter interlock bar bent. So I’m gonna replace on that. But I also noticed a lot of forward/ backward play in main shaft. I tried to load a video unsuccessfully but if I was to throw a number on it I would say 3/16 to 1/4 inch. Is this normal or do I have larger snap ring or bearing issues?
