I do not believe the Impala glass is the same..pretty sure but not 110%. I think these x-frame pontiacs are the same frame ,drivelines, gas tanks and related parts, front end suspension bits and brakes etc. Once we start moving above the floor boards I think stuff changes between chev and pontiac. Bodies are canadian pontiac only I THINK. There are dimensions..ie whl base etc online for our cars and the american pontiacs as well but be forwarned all is not gospel regarding these cars.When I figure out how to manufacture time I will delve into this mystery head first! Til then I must say that there are indeed much more knowledgeable fellows here than me. Having jibbered all that please post back any of your findings!!
Id say it is the same, 63 and 64, 100%. Even the glass trim is the same, inside and out, most of not all, except Pontiac May have more chrome inside on the Parisienne.
