FRONT BUMPER BRACES ..

[PaPitt]

so My D250 is a 1988 that I'm working on at the monument. & i'M ABOUT TO TRY & PUT ON a new front chrome bumper . My 1988 braces are bent rather bad. But I have about 4 older dodges down on Bronco Row . maybe 1972 to 1976+r-... Not sure if any have good bumpers braces or not ... But I expect some do.
.... Does anyone know how far back the braces are the same . Year models please.
THANKS In advance ..
