Just remember Tasca Parts aren't consistent, I've had quick hassle free orders but everyone is different and resolving them isn't easy. I've had orders where they've added random parts (F150 door handle), where they haven't updated the order and sent the wrong part (had to claim on my credit...
3 parcels shipped at the same time, from the same place for Thursday delivery:

We have completely different part numbers too, it's a way for Ford to discourage us from buying from the US, so they can charge double or triple the price from UK dealers.
I usually do my own research on the parts and then untick the VIN check because it throws up lots of incompatibilities even when the parts are fine. Tasca also don't hold the parts so you generally have to wait, so my order I placed 6 days ago has just been shipped.
OEM parts (From the US) are cheap enough to not have to buy used. Me, I'm waiting till mine are completely worn out and replacing them with the GT350R kit.
