Y Block C4 conversion

So I have a 292 in my 59 F100 with a Ford-o-matic. I dont much like this transmission so I have begun collecting trans parts. I have done my research looking for the proper torque converter but I am still unclear. I talked to the guys at Ford-Y-Block and read elsewhere that the proper torque converter is an 11". I cant find an 11" torque converter for a C-4. I have found plenty of 10.5" or 11.45".
Has anyone done this conversion that can give me a part number or at the very least verify which one I actually need? I know this is a common conversion so someone has to have the info. I have looked through a good amount of c-4 forums both here and at other ford forums and cant find the answer. i appreciate any info.
Also if you have any nice to know info regarding this project please pass it along. I think when I do it I will do a build thread and include a complete parts list with suppliers and part numbers to help anyone in the future. Thanks.

 

Here's a link to how it's done: http://www.y-blocksforever.com/tech/html/c4conv.html

 

So I have all the info I need on parts with the exception of the Torque converter. Can someone please help.

 

11" torque converters.

Simple, choose the stall speed you want and go from there. The Flat O kit has everything else you need.

I picked up an affordable starter, I just went into the local parts store and asked for a starter from a 1970 Ford pickup with a 360 engine.

 

The link that Easyissy gave had everything except the torque converter id. It did have an email address way down at the bottom though. I don't know how old that link is but i think I'd send the writer and email asking what torque converter he used in the swap.

 

In that article he mentions that the C4 came from a 1970 Mustang. I'd be willing to bet he put another torque converter into the conversion that was specified as being for his 1970 C4.

Choose a torque converter from the suppliers (11") and specify the year and model of your C4 and you won't have any troubles.
