Classic/Antique Car Repair: ford three on the tree with od, hemmings motor news, stock answer

Question
I have a 1964 galaxy with a 289 and a three on the tree with OD, unfortunately my overdrive unit is broken.Do you know of any company that sells a rebuild kit, I cant find anything and am getting to my wits end.

Answer
My stock answer for “where can I find….” Is to latch on to a copy of Hemmings Motor News, the old car hobbies classified bible. There are many companies that supply parts for old cars, trucks, and now RV’s and you will find them in Hemmings. www.hemmings.com
