Update
It's been a busy week. I made some good progress, and ran into a few "issues."
Issue 1 - headers.
The BBK Mustang headers (what I swapped the JBA Mustang headers for) fit perfectly on the passenger side (not counting the frame rail that needs clearancing.) The driver's side, however, is a different story. The #2 tube and steering shaft want to occupy the same space.

(Only minor frame clearancing is required here.)
I have decided to swap these for a set from L&L. The L&L's are designed for this specific swap. I called yesterday to ask some questions
before ordering the headers - I am waiting for a callback. Assuming I get the answers I am expecting, I will be using these headers. Let's hope they fit.
Issue 2 - Advance Adapters AOD-to-1354 adapter.
I spent a good part of the day on Saturday making this overpriced adapter fit as it was supposed to. Had the trans and xfer case
not been under the truck, I probably could have done the required mods in about an hour. Had AA built it properly, I wouldn't have had to modify anything.
Needless to say, I am very unhappy with the sloppy workmanship of the AA adapter. But, they are the only ones making one. I expected a better fit, given their reputation.
On to the good -
Transfer case completely installed, as is the rear driveshaft. (Leaving the front out until the transmission shifting is taken care of.)
External oil filter installed and plumbed. AN-10 steel braided hose is
interesting to work with.
Trans cooler hard lines installed.
Fan controller wired.
Radiator mount complete.
Fuel rails installed. (Plumbing tonight.)
The bracket holding the trans shift cable on the A4LD
fits on the AOD! (One less part to buy...) However, part of it mounts to the part of the adapter that I had to modify, and it positions the cable too far away from the shift lever. So, I need to fab a new mount, and weld the bracket to that.
To be fabricated -
Shroud/fan mount
Trans external oil filter mount
Trans shift cable mount
Now that I read this, it looks like a really short list, given all the hours I have spent with the truck.
