Idler Arm bracket for '65/'66

About to start doing the V8 suspension swap with Granada brakes.

I just need to know if there is a difference between the idler arm mounting bracket between a 6cyl. and a V8 car.

NPD only lists one, but my Restoration Guide gives 2 different part numbers;
3350-1 = T-code
3351 = C, A, & K-code

Also, anybody care to double check the other stuff on my steering component list?
-V8 Drag Link
-Granada outer tie rods
-V8 Mustang adjusting sleeves
-V8 Mustang inner tie rods(still need to get)
-V8 Idler Arm
-V8 Pitman Arm(still need to get)
-Idler Arm dust cap

Starting from scratch sucks, but at least everything's new.

So I've stumped up to 33 people?

I'll just assume it's the same. If it doesn't work, I'll order the NPD piece since it's practically overnight shipping where I live.
