Trim yoke/jackscrew threads

[Jeff J]

I am trying to replace my trim yoke without cutting fabric. The jackscrew looks good so I only ordered a yoke from Unvair. I had no trouble removing old yoke. It is different than the new yoke. It has a removable brass nut in it. I got the new Univair yoke in position but the jackscrew only seems to go half a thread and stops. Are there different thread pitches/sizes preventing the mixing of parts?

Thanks,
Jeff
