So this part did not give you an option for 2 or 4 wd. It says it fits all models, I have determined that's a lie. it does not fit a 79 F150 4x4. It may however fit a two wheel drive. But for me all it did was create more work/ hassle because now I have to deal with the replacement instead of working on my truck. I am sure the part is fine it's the sales and marketing that need fixed.
