2WD or 4WD Front Splash Seals

[AKguy]

Getting ready to make an order and need answers. I am using my 1981 C20 Front/Cab and bed to mount on my 1979 K30 frame and running gear. What’s the difference between the 2WD and the 4WD front splash seals? Are the inner fenders on the 4WD different? Thanks.

I believe the 2wd ones have more "cutouts" along the bottom edge for the A arms range of motion but haven't compared closely since my resto aint to that point yet.
