Throttle body supposedly came off a 2003 Cadillac Northstar 4.6.
I'm trying to get all my parts lined up for my 3800SC Series III swap and thought I needed a 2000-2005 Northstar throttle body and a L36 gen 5 adapter plate which is what I thought I had purchased. None of the holes in the parts fit together or line up.
Adapter plate from ZZP is the "Gen 5 to L67/L36 Throttle Body Adapter Plate"
They do not line up with each other in any way, shape, or form.Where did I mess up?
