I tried at a few different parts giant Ford stores, but couldn't find one for that price.
We got lucky. There was a batch of about 8 that were take-offs at a Roush shop. We got a great deal.

Need a question answered real quick, is it better to just re-use the 15-17 throttle body or would using the 18 throttle body be a better idea?

Use your original throttle body. An '18 TB will give you no benefit whatsoever.

Fairly certain the 15-17 and 18+ throttle bodies are the same. The 15-17 bolts right up to the 18+ manifold. So just to eliminate a variable during install, probably easiest just to re-use your stock one.

Hassle only comes when attempting to use the GT350 throttle body, where you need an adapter plate and careful tuning by your chosen vendor.

So I'll probably just lock out the IRMCs with zip ties, is there anything else I need to purchase for the manifold swap or should I be good?

Just some vacuum hose if you don't have that on hand already.

Oh wait what about the plug and play harnesses everyone mentions? I'll need those if I don't want to do splicing myself correct?

Just lock out the IMRCs. Just got my swap done and I don't notice any torque loss (except in 6th when really lugging the engine, but I have a 6R80 which has two overdrive gears).

Oh nice, so by locking out IRMCs I don't have to do anything else with electrical/harnesses? Just bought the Intake Mani, trying to get everything else ready I'll need besides tune

They fit the same but are not the same. The 15-17 TB is analog, 18+ is digital. Can't use the 18 TB on the 15-17.
