1978 GMC 3500 bushing kit

[78 Bonanza]

Have been looking and calling all over trying to find a complete bushing kit for my 78 2wd crew cab. I called energy suspension and they don't have all of the parts I need. Has anyone else restored their 3500 and run into the same problem? I'm ready to put her back together and would appreciate any part numbers, kits, etc. that are out there. ES rep. told me they have the front sway kit and the body kit but nothing else. ?????? Thought that of anyone they would have a kit or at least the parts. She is all stock and never had anything changed (I'm the second owner). I have a car show to attend in 2 months so I am in a bit of a rush. Thanks.
