85 Suburban Control Arms

[jumbo]

not to hijack your thread, but i need upper control arms for my 89 burb. I have the porterbuilt dropmember, it was made for stock arms, ART arms, or Porterbuilt arms. The guy that built my burb used Dallas Hot Rod arms, and they're a couple inches too short (when i raise the truck up i have serious negative camber issues). My father in law has a frame from an 80 half ton c10. Would the upper arms from the 80 work on my 89 burb? Thanks in advance....
