Inner fenders : which models are the same?

[Camatruder]

Hi guys, this '91 K5 is my DD. Both front inner fenders / splash shields are toast due to salty roads in winter time. They're only 50 each at rockauto but about 1000 to ship overseas. I'd like to find a pair of good used ones on a USA car junkyard, which are not numerous here. So i might have to travel a bit and it would be great if i knew which GM's used the same as mine. I would guess all late 80ies GM trucks no matter what engine or driveline but really i don't know.
Thanks.

Yep, all '81 and newer squarebodies.

73-80 will also work in a pinch if you open up or ad a few holes.

Good luck finding a 73-80 passenger side that isn’t rusted out. I looked for months for mine, only to end up buying a new one from rock auto for about $30. Apparently every battery ever made leaked acid.
