So I found a 2000 3500 1ton with IFS with 410s will this setup work under my half ton 1999 Tahoe I run the code on gears 410 but not trans I think 400 and 454 motor but going run them but just wanted to know if this a easy swap or modes need to be made. I looked it over and looks about same ? I do have 3 sup and 3 body lift now on 35s but just a curser with 342s I may go NV4500 but not sure yet thanks for any info.
