89 6.6 Ford Brazilian engine to a 545 Allison transmission automatic
 

Gentlemen, I’m new at this, so please bear with me I have a F700 It came with a 82 Detroit engine. The engine had a bad head gasket so I’ve taken it out attached to it was an Allison 545 automatic transmission. I have purchased a Ford 6.6 Brazilian engine. It had an Easton five speed manual transmission I want to put the automatic transmission the 545 on the 6.6 Well, I have to change the flywheel on the 6.6. What adapters will I need to use for this process and where can I find the parts thank you
