Sway bar

[Z28Owner]

I have a 71 Chevy C10 2wd and LWB with no sway bar, I would like to add one. Anyways I went to a junkyard and the guy said that the 73 and up frames are wider and the sway wouldnt fit, I thought I read on here somewhere that they would fit. I cant use the search right now its down. I found a 2wd 73 chevy with a full sway bar on guy said I could take it off for $20. Is it worth my time how hard is to get to fit my truck? Also I am goin to grind the rivets off and I noticed it is connected at the lower A arm too, Is this part bolted on or how do I remove it, I only got a quick look at. He was closing up, I am goin back there tomorrow if you guys say it will fit with little ease. TIA -Jason
