Is there a distinctive way to identify the main dash harness for 1970 vs 1971 vs 1972? I found a dash harness in my parts yesterday,and it is absolutely perfect. If it is a 1970,I would like to use it. If it is another year,I’d like to sell it.
Hey Brian, here is the tag from my dash harness from a 1970 Buick GS Stage 1 built Jan 1970. Automatic, console with ralley gauges (temp, oil, gas) and clock in dash. My assumption is that its the original, it was pretty old and cut up. It shows an SH and 3769...Now I don't think there are 376 days in 1969 so not sure what that code means.
