I'm beginning the restoration of my 1985 El Camino, this will be the 3rd time since I owned it. I'm looking for the drip rail forward pieces, I got a couple of sets that may be salvageable. I set has rounded (smooth curve) corners that I prefer, but the ones on it presently have the angled curve as does one of my old sets. One of this set has some damage and don't know if it is repairable? Does anyone know which model the smooth ones were installed on? Without taking one off I don't know if these will fit. Look similar but there is some difference? Has the the design of the from windshield posts changed from the 78 thru the 87? I don't know of any but there's a lot I don't know about.
