Are all the k-members the same or did they change from 3.8 N/A 3.8SC 4.6 5.0??
Actually there's 5 Ford Part Numbers for the K-Member..MadMikeyL said:Just because there are 2 different part numbers is no guarantee that there is any physical difference between the 2 parts. Part numbers change and get revised as time goes on, so it may be as simple as that.

The original MN12 K-Member was Ford Part Number: E9SZ-5C145-A
Then with the introduction of the 5.0 in 1991..Ford changed "something" on the K-Member..That Ford Part Number being: F1SZ-5C145-A
Here is the other 1991 K-Member Ford Part Number: F1SZ-5C145-B
The introduction of the 4.6 DOHC in the 1993 MarkVIII led to the latest K-Member: F3LY-5C145-B *note the Lincoln "LY"
IMO..The F6SZ-5C145-A part number was just a part number update..Unless someone can prove otherwise..
There must have been a difference in the K-Members in 1991..In order for Ford to have 2 different part numbers..What difference that is..I don't know..
I'm not arguing with you..Just putting the information out there for discussion..
That's true..If it was Cougar specific it would have the "WZ" in the part number..XR7-4.6 said:F1SZ is 1991 Thunderbird service part. If it was Cougar specific it would be F1WZ.
When you're looking at the part numbers on the back of a part..You might not even see the actual Ford Part Number..I see that happen all the time..XR7-4.6 said:I have piles of identical parts with the same part numbers, from the same year car, just ending in -As, -AAs, -ABs, -Bs, -BBs, ect, ect.
