I have a turbo F-Body that has already been converted to OS 2020005 and I am looking to swap my 4l60e to a 4l80e. Can I still just do a segment swap from a truck with OS 12212156 since that is was 2020005 is supposed to be based on or do I need to go about it some other way? Also, if I can just segment swap it, does anyone know where I can get one for 12212156?

Thanks
