Where to buy aftermarket manual Columns?

[Chris04]

Hey guys I got a 3 on tree manual column in my 70. I have replaced the bushings and it fixed some of the slack but it jams all the time and doesn't want to go into gear especially 2nd and I will eventually tear it apart and prob fix all the issues. But I noticed on eBay and other company's make a automatic aftermarket ranging from $300 to 800 bucks but all I can find is automatic columns! Do they not make manual columns? Or I just can't seem to find them. I would rather just buy a new column than rebuild mine but not having any luck finding anything. So any suggestions of who sells them? Thanks
