No first or third gear
I have a '75 vert last winter I did a 4spd conversion. Installed a super t10 with a hurst shifter. I was told the 4spd was rebuilt. Upon installation I installed new clutch, bronze bushing , new throw out bearing. Now after about 800 miles the trans won't go into first or third gear when I try to shift into those gears it grinds. Any help would be appreciated thanks

I am hoping its the shifter linkage needing adjusting. The clutch linkage looked good and tight.

Rookie here.......I had a similar problem back in the day that kept getting worse..........the trans would "ease" out of 3rd gear/it worsened until the trans would "pop" out of 3rd gear/finally it started grinding going into 4th gear. I vaguely remember something about the bronze synchronizers and a scarred gear shaft.
How is the oil level/does the oil look "dirty or thin"?

I really hate to break the news to you but I had the same exact problem that you described after putting everything in new and it turned out to be a defective bronze bushing . I bought it at Advance auto parts and told them that I wanted their best stock bushing . The tolerances were too tight and it seized letting the front trans shaft keep spinning causing the grinding . I bought a good quality needle bearing at Napa and it works fine. All of that work because of the cheap crap that they are selling.

get under the car, disconnect the linkage and push the side lever into gear to see if it is an internal problem or a linkage problem

If it is the pilot bushing seized then the front shaft would spin all of the time and will grind if you try to put it in any gear when the engine is running . I think you will find that to be the problem . There seems to be a problem with the bronze bushings.

Ok , I fixed it. It was the first/third gear shift stop. It had come loose and backed out. So I adjusted it and tightened it back down. Man I am so glad it was an easy fix. Thanks everyone for your help and suggestions
