Lower control arm bushing issue

[KMAT]

I don't know if anybody has had as much trouble as I have had regarding lower control arm bushings trying to figure out what the front end of my truck came out from as a donor front end I have a 67 C10 short box Stepside the front has been updated at one point to disc spindles in upper and lower control arms well I'm redoing the front end bushings ball joints tie rod ends all the works drop spindles and none of the parts stores where I live have been able to figure out what it came out from so I can put in new lower bushings we've tried everything half ton from 76 through 87 pick up and the bushings that they have gotten for me there's too much play when I slide the shaft inside of the bushing if anybody can help me and I would much appreciate it I only have a picture that I can post as to maybe someone might know what these might come off of. Once again ANY help or advice would be much appreciated
