I have done some research using the search function however I did not see anything that answers my question. I am collecting the parts necessary to do an Eaton swap on my '03 Supercrew. My question is in regards to the harmonic balancer that I will need for the swap. I have the lower caged pulley assembly for a 99-00, it came with a flange that appears it would bolt onto a balancer and allow the caged pulley to thread on. I did a search on the White Bear (formerly Tousley) website for the Ford number on the 01-03 Lightning stock balancer and its the same number as the NA balancer. Will that flange bolt to my OE balancer? If not, is there any reason that an 03/04 Cobra balancer would not work? I have a nice low mileage version that looks like would allow me to eliminate the flange entirely. Both my truck and the 03/04 use a 6 rib inner belt so that is not an issue.
I understand the 99-00 and the 01-up have some differences. I am curious what my best option is?
