Three-On-The-Tree bushing kit

Hi guys,

Do any of you know where to get a rebuild kit/or parts to rebuild the column shift mechanisms in the column?

We have a 70 Dart that we rescued from a 30 year slumber (then took on the 3000 mile Lemons Rally last July). Got the car running great, and now would like to fine tune it (fine tune being relative).

Thanks,

T.
