EMERGENCY INFO NEEDED - 3 speed manual from 67 Dart

I'm drawing on info thats stored in books I've yet to unpack, so I may be wrong on some of it.... So, if I recall correctly....

The two 3spds that were used most were the A250 and A230. The parts aren't all interchangable, since the helical cut on the gears was different angle from one to the other. The A250 was the stronger of the two, but neither was particularly V8 material. They will both bolt to the proper bell housing, if the correct input shaft support is used. The main difference is the diameter of the flange that centers the trans on the bellhousing. The shifters are different from 3spd to 4spd, one has two levers, the other has three.
