I am looking to buy 2 rocker arms and 6 acorn nuts to fit the heads on a 89 turbo trans am. Alternatively, the rocker arms and acorn nuts off a 1980's GM 3.0 liter front wheel drive car (probably Buick or Pontiac) will work too. I have canvassed the wrecking yards in Anchorage, AK and cannot locate the parts I need.
