Just went to the 4 wheel parts warehouse here in OKC and ordered a Smittybuilt prerunner bar for my 79. According to them they are discontinuing that style for the 73 to 80 years Chevy. They had two in stock so I got one and Chris, a K5 fanatic who if you want to know what will or what wont work and where you can get it, he's the one to ask, ordered the other for himself (he's the only one I deal with here). I've looked at all the other manufacturers, and Smittybuilt seems to be the only one who makes one for this year group. Anyone know who else makes one???
