ToddRon's kit is for use with the "Ford" version of the T56 Magnum and the matching Quicktime bellhousing for a small block. I started with his kit and modified it heavily to get it to work with a "GM" version of the T56 Magnum and the matching bellhousing for a big block. APT recommended to me to go the with the combo I did for some reason due to the clutch, I don't remember the details. The ToddRon kit is quite stout and does require considerable fabrication even as is for a small block.
