HELP PLEASE!!!! Steering Issues

[EVBuilder]

I have a 1963 GMC C-1000. The front suspension was changed at some point to what I was told was 1984 full size van 1500 series. I had a loose tie rod end and thought that the hole in the spindle was worn out from the nut being loose but when I put a replacement spindle on, the tie rod end is loose in it as well. Does anyone know what tie rod end would work in this truck? What do I need to change to make the steering work properly and safely? This is my main mode of transportation at the moment and need it fixed ASAP.
