I think the answer is yes. However, I bought a repro trunk pan for my 66 (I bought an Impala pan) and the while the dimensions were fine, the channels stamped into the pan were in a slightly different spot. After reading online, it seems that the trunk pan sold is somewhat generic. It is the right size but over the years the "pleats" were in different spots and the aftermarket has chosen to sell just one pan for a number of years, I think 65-70. I am not sure if that means it will be correct for your 70, or some other year(s) but I can say for sure it needs some massaging to fit 66.
