My May 5th 70 chevelle was T3 also and she is a canadian car.I just don't remember seeing these in the early 70's but they must have been there since that is when I gathered the box I had. I always thought they were a GM over the counter replacement for the T3 but that is probally wrong.If not man did I leave a pile of NOS ones laying on shelves that I could have had for pennies a light over the years.
Someone out there will know the dates
