Transmission not shifting

[dareguy]

I knew that sometime I would be posting this. I have had issues with my transmission since it was "rebuilt". It has popped out of reverse on a regular basis and the second gear syncro was not working ( series III transmission). Today I shifted from reverse to first gear and that is all I have. The lever moves around like it is in neutral and no other gears are working. I do hear grinding noise coming from the transmission. So, knowing that I am screwed, where would be the best place to get a rebuilt unit. Going back to the guy that rebuilt it is not an option.

Thanks
