I've gotten lots of parts from LMR that are just Dorman, Pioneer (speedo cable), etc. I've started looking them up on Rockauto and a lot of times the numbers and pictures match. So for example the Speedo cable. $26 thru LMR. They happened to be back ordered when I got one. I wanted the LMR because I thought they would sell the best fitting part because they had it produced. After waiting forever I just asked was it a Pioneer part and they said yes. Pioneer factory is 15 miles from me. O'Reilly auto had the exact one on the shelf for $13. So my point is, lots of their stuff is straight from parts stores...some not. So I'd agree to run the Motorcraft part. If not, at least check they aren't just selling you the exact part you can get anywhere for half the price.
