[Chevelle-List] Four Speed to Automatic

[Lojac]

Can someone out there please tell me everything I would need to convert by 69 Chevelle from a four speed to an automatic?  The car was originally an automatic, so I think there are still some of the linkages under the hood (???).  I was thinking about a Turbo400...any thoughts.  Anyway, I just wanted to know what I needed to do the swap.  Does anyone make a kit for this swap?   Thanks, Lojac
