change from manual to automatic

[rizick]

I am wanting to put an automatic in my 66 stepside. it had a 6 cylinder with a 3 speed manual. I found a 327 from another 66 and currently we are rebuilding it. Any ideas or suggestions would be helpful, I have changed a few engines and trannys but cant say I have ever converted from manual to auto and would like to keep my mistakes to a mininum. Kind of thought about a 3 speed auto or something with an overdrive. I am worried about linkage and the drive shaft issues, I am sure I can find a automatic tranny mount, and was thinking about a tiltsteering column from performance parts or someone like that.
thank you
