Parts for 1987 Sub

I am looking around for Off road type parts for 1987 Sub. I can not seem to find things like grill guards side steps ect for this year. Any ideas? Thanks

just an idea,, if you could finding a grill gaurd off either an M1008 or M1009 which where the military pickup and blazer. im pretty sure those would bolt direcly onto your bumper. They are nice and it would be easy to paint one to match the sub's color. I know ive seen them on ebay before.
good luck
