2 Door vs. 4 Door

I want to replace the front fenders on my 91 Regal as they are starting to rust out and that is the only place on the car where there is rust. There are a number of 2 door models being parted out in my area by various individuals and I was hoping that I would be able to get fenders off of their cars for mine if I can find the right colour. All of the ones being parted out are 2 doors and mine is a 4 door, would the fenders be the same or would they not fit? Thanks

2 Door and 4 Door regals have completely different sheetmetal
Fenders from 2 door cars would not fit 4 door models, they have simillar size but different cuts and style.
Take a look:
