Will the dashboard from a 1997 gmc or Chevy truck match interior of 1990 sierra?
No, a dashboard from a 1997 GMC or Chevy truck will almost certainly not match the interior of a 1990 Sierra. The 1990 model is from a significantly earlier generation, and the dashboards are completely different in design, shape, and overall styling. Even if some parts *might* be similar in size, the fitment would be off, and the overall look would clash badly.
